Good boots (that trail has some water and mud on it) for rough trails with rocks. Make sure that you get fitted by a person who has been through a training program that gives a certification. The process they should put you through is a thorough understanding of your skills and your hiking goals in the next couple of years. They should measure your feet sitting and standing and standing on one leg moving to keep your balance. They should inspect your previous boots/shoes and spend some time looking at your feet for unusual bumps and skin thickings. Once you get a boot (HEAPS of toe room), you should wear it around the store for 20-30 mins. The fitter should be able to push at different places and ask it if is tight or has some pressure. They should be able to trade out a different kind of boot that will fit better and should have a boot anvil (looks like a large S made of steel solidly connected to floor) that they can work on places that the fitter has marked that she knows where to move the leather a round a bit. You can get generally two kinds of boots/shoes. Fabric and leather. I like fabric if my feet are going to be wet. They dry faster. Unfortunately they will be more apt to give you feet problems after a lot of use (years). Leather comes with a shank that can be full (for clip on crampons) and 1/2 or 1/4 shank for more trail work and strap on crampons. I have always preferred heavier boots for long days on rough trails with a heavy pack. Others don't - you should find out in the next few years which you like best. I am not sure that the waterproof breathable fabric liners are worth it considering what they do.
Good pack that fits you well and will carry 20% of your body weight comfortably. The packs made in the last 10 years are far superior to those the decades before. If you are going to spend money on a piece of gear this is where you start. You should rent or borrow or spend a lot of time looking at others on the trail are using before you get one you are going to end up with. I like internal frame because of the general feel. I grew up with external as a kid and carried awesomely stupidly heavy loads. I like my internal. Sooo many to choose from and depends on what fits you and your style. But in most cases, so long as it fits (the store should measure from the knot you feel on your spine just above your shoulders down to a line between your upper hip bones (iliac crest). A woman's fit is different from a man's. They should be able to explain the difference. I like a couple of external pockets to put small stuff in that I need all the time
Get the best 20F sleeping bag and pad that you can afford. I prefer down for lots of reasons. Rent/borrow a couple of different kinds to see if you like one over another before you invest. I really do like my 20F- down quilt - for summer.
The simple propane canister stove would probably do you for a week. Any longer than that and the weight of fuel and the kinds of food I like sends me to my MSR Dragonfly. I used an old brass SVEA stove for years. I still roar it up just for old time sake. It works like brand new.
Pots and pans don't have to be titanium unless you have some really well heeled friends that accept dropped hints. But the size you need is on the order of:

About a liter, and aluminum is about half the price and works better. I put two plastic stackable cups, Snow Peak stove, fuel can, two small BIC lighters, a Lexan Spoon (spare in bottom of bag some where) and pot grabber inside the pot and I'm ready to go. If you plan on cooking, a small light weight fry pan has lots of uses if it is deep enough. Most of our meals are based on water and are dense (pasta, rice, pita bread, peanut butter, etc). You will be exerting around 400-600 Kcal and hour up hill with a pack. You have to figure out how you will be replacing that with many small meals a day and a few bigger ones to take up the slack. Probably won't do it with freeze dried. Check the package and calories per serving. If you pack any food, repackage it into zip locks and crush it flat. Don't forget the instructions AND what it is.
You can use some of the things from your backpack for car camping. One thing you might find handy is a 12x12 foot light weight tarp with a grommet in the center to hold a trek pole tip set up on a picnic table. Grommets on edge let you guy it out so you will have shade and rain protection. We made a denim roll-up with pockets for kitchen ware and eating utensils. Loved our Coleman 2 burner stove.
A large collapsing plastic water container makes a lot of sense. You can hang it from a tree and one trip might do you for dinner and breakfast and wash ups.
I won't go into tents. That is an art unto itself. Tarp tents are nice and the more expensive and heavier ones are even nicer. I like my very expensive Stephenson Warmlite tent. It has paid for itself many times over in trail sweat. If you have lots of bugs, a tent makes more sense than laying in the open on a ground cloth (I do that a lot anyway) or huddled under a tarp.
Plan on mosquitoes in the Rockies. DEET works. Just don't put it on like sun lotion. Just a drop warmed up in rubbed hands and wiped off on clothing and exposed skin works for a couple of hours. About all you normally need, in the evening and early morning when they are active. But you should have a hooded jacket (I like my $30 Precip), a 200 fleece long sleeve to go under it and to slip on when you stop for a breather on the trail. Don't forget the uv lip balm, high SPF UV screen, hat, and sunglasses.
Trek poles are not rocket science and neither should you pay astronomical prices. My selection was based on weight, size collapsed, price. I like Komperdells at $50/pair SierraTradingPost.com. Just keep them clean and maintained and the twist lock will probably be all you need. I like cork handles with no kant, springless. That little strap is what makes the difference between a hiking stick and a trek pole. Learn to use them the right way and you will be well rewarded. Check out

Planning on spending a couple of nights in your back yard to make sure everything works the way you expect. Then, as somebody suggested, take it for a spin locally.
Get these books and skim though both in an evening while putting sticky notes on the parts you want to read in depth.
Mountaineering: Freedom of the Hills
The Mountaineering Handbook, Craig Connally ISBN 0-07-143010-5
It is a good companion to Mountaineering: Freedom of the Hills. Connally puts a good, reasonable approach to getting ready for and doing any kind of hike.
You will save more than the price of the book just on gear, clothing and time it takes to get ready for a hike.
Have fun out there. That is what it is put there for.
