Donkeypunch,
Gear is very much like a car -- some people swear their Mercerdes is the best thing on the road; others (like me!) think you can get by with a Toyota or Mazda. Ultimately, it's the individual user that decides.
I was fortunate to get my feet wet years ago on some 7-9 day hikes in the Sierra Mtns (CA) with some very knowledgeable guys, and one thing (looking back) I learned is that "know how" is not acquired by buying the best gear at REI but rather by spending time on the trail! So if you can find some guys to do a few weekenders in Western WA, that'll prove hugely helpful. It's a great way to sample gear without having to buy or even rent! And you should have some excellent resources for that right in your backyard -- the Cascades.
Some other tips --
*Start with 3-season, weekend trips. Winter camping requires more experience....and can be much less forgiving if you make simple newbie-type mistakes. And I can't think of a single 4+ day trip I've been on in which there wasn't at least one 'issue' that came up along the way -- that's when your experience is needed the most! So think baby steps....
*Speaking of baby steps, beginners will err. Just accept it. Heck, I'm sure the seasoned vets in here still have mishaps! I know I do. All of us could give you stories, either ones we've seen or experienced ourselves. Another reason to keep it simple when starting! Because that's when you're most likely to make a *really costly* mistake.
*Make sure you try out new gear that you've never used before. You'd be surprised how many people will never pitch their tent or start their gas burner until they get to the campsite with 20 minutes of daylight remaining, rain pouring down, etc.
*If you've done hiking a lot, then you know the importance of getting a good fit with the right boots. This is one place where I've learned not to skimp. An inexpensive pair may feel ok at the local Big 5, but strap a 35lb backpack on....and see where things are after 5 days. One thing I learned is that you can get away with not having *great* gear in all sorts of ways....but the quickest way to make a trip miserable is when someone starts getting feet trouble. There may be a great budget shoe out there, but I've not yet encountered one.
*Packs are like shoes -- try before buy! You could get lucky by buying some closeout special online....but my guess is that more times than not, you'll end up with a less than perfect fit.
*The differences between a 45L and 85L is not simply about volume. 45L is really a perfect starting size for weekenders. You might think, "Why not get something bigger to work up to?" Well, many packs above the 70L mark don't pack down smaller loads all that well in terms of fit. And you may not really be able to tell that in the store. So if you buy something up around 85L, I would make darn sure someone who's used the pack a lot can verify whether the bigger pack can firmly carry a smaller load. My suggestion would be to shoot for something in the 45-60L range for a first pack purchase.
*A great example of expensive not always being better is down vs. synthetic in the bag department. Lately, I've been using the Mtn Hardwear Flip bag, and I am blown away they made a very functional 3-season bag that weighs in at only 2 1/2 lbs. And I only paid $72 bucks for it (with discount)! Frankly, I think I like it better than my 3+ season down bag that I paid over 2x more for. There are a lot of recent synthetic bags that pack quite small 'n light...and usually for significantly less than down.
*Different people sleep different....which means there's no one-size-fit all about bags and sleeping pads. I finally ponied up almost a $100 for a Exped XL sleep pad...but that's because I sampled a lot of other pads and figured out that I just couldn't get a good sleep on them. In hindsight, I realize how easy it could have been to drop $75 on a highly-rated Thermarest pad....only to realize that it would have been money wasted in my case. This is where trying to sample gear (when possible) is really key. If you can't sample it on the trail, then at least try to sample it in the store -- a good outdoor retailer should let you 'try on' anything from a tent, to a pack, to a sleeping pad.
Lots else I could say....but I'm sure most of it will be covered far more competently in other forum threads.
