If you are truly clueless as to what you need, the first thing you need to do is read a good book on hiking and camping such as the latest edition of "The Complete Walker", which is widely considered "the Bible" of hiking books. "Freedom of the Hills" which is about hiking and mountaineering is another excellent choice.
You need to understand what you need before considering brands or specifics. Other factors include where and when you will be doing your hiking and camping.
Camping gear can be broken down into systems (The Complete Walker does this). You have shelter, sleeping, clothing, kitchen, navigation, personal safety and probably a couple I can't remember offhand, but you get the idea.
You want the individual pieces of gear (clothes included) to complement each other, not just be random stuff that someone gave you or you bought because it looked cool. This is especially important with clothing, where layering for cold weather is the tried and true method. I carry enough layers in winter to go from a hot sunny day in the 50's or 60's to around -20F or so.
For example, I have a Swiss Army knife. I bought my particular model because it has a phillips head screwdriver that fits the screws on a bike derailleur. I have a ratchet screwdriver with torx bits to fix my ski bindings, also not something most people would need. Much of my gear is tailored for the Sierra in winter, so giving you my gear list would be next to worthless for someone not doing what I do.
I have no need for a Spyderco or any other Rambo sized knife for any reason. I do have a fairly big fixed blade knife I bought to take whitewater rafting, but I consider it a special purpose knife and I have no reason to take it camping. I learned this lesson when I bought something the size of a Bowie knife when I first took up scuba diving. As time went by and I got a lot smarter, I bought something much more useful and about 1/3 the size.
My knife does most everything a Spyderco will do (like cutting up cheese) and much more because of the tools on it. I probably couldn't field dress a deer with it, but I couldn't do that with anything anyway no matter what it was and unless I hit one with my car, my need to be able to do that is zero. And unlike Han Solo, I have no plans to be cutting up some huge animal and climbing inside it to keep warm. That's what my sleeping bag is for. On the other hand, the little scissors, screwdrivers, and bottle opener are pretty handy. So is the little magnifying glass for looking at splinters in your finger.
There are many sites with gear lists for different types of hiking and different weather conditions. Check them out, but start by reading a good book. It will be worth it.
