+1 to what William said. Being new does not mean you can't start out Light or Ultralight. An Osprey does not help you meet that goal.
Hope it doesn't sound like we're picking on you, but here goes :-)
I also agree with William that you've spent too much on that tent. Check out tarptent.com for Harry Shires' very innovative and relatively inexpensive UltraLightweight tent designs. I suggest you return the pack and the tent.
Western Mountaineering makes beautiful and very expensive sleeping bags. Is a 30 degree bag going to be warm enough to suit your needs? Most people come up with a "sleep system," layering in more clothes and a lighter sleeping bag, or, as in my case, less clothes and a warmer bag. It depends on how warm you are naturally and what conditions you expect to encounter on the trail. I tend to be quite warm in general unless there is wind and sleep in my clothes. YMMV. If the MegaLite's rating works for you, it's an awesome bag (I'm a former HighLite user). Keep in mind that if that bag, especially, gets wet, you might as well not have it.
As for your list, sleeping pads are a highly personal thing, and if this thread catches on, you will get as many opinions as responses about them. Some people sleep on a whisper of blue foam, some people can't live without a thick pad. Some people are very comfortable with torso-length pads, and sleep on a ProLite XS- 8oz, but only 36" long. Too short for me. I have an inflatable Big Agnes Iron Mountain, which I'm not in love with, and a ProLite WOMEN'S. Why women's? 6 inches shorter at 66" than the men's but a 2.8 R-value for the same weight.
I encourage you to go to REI or someplace where they have floor models of sleeping pads, and lay down on them, right there in the store. Don't be shy, just do it. The REI Lite-Core is also a decent pad for the money.
Cooking is someplace you can also spend a lot of money for no reason. My stove weighs less than 2 oz and it's made out of 2 beer cans, a piece of tinfoil and a coat hanger.
I learned a lot about it from this site and from following the links:
Rope? For bear-hangs? Check this out: http://www.backpackinglight.com/cgi-bin/backpackinglight/bear_bag_hanging_technique.html
There are a million lightweight cords out there. Ask at the hardware store or outdoor store. In my experience, everything is cheaper in the hardware store.
A bear canister is important if you're in an area where it's required, or if you are unsure about your ability to appropraitely hang your food. A hot topic of discussion around here, for sure. Just remember, protecting your food from bears is no more or less important than protecting bears from your food.
You will also want to really think about clothing. A lot of the clothes sold in outdoor stores is the Emporer's New kind. Having a light pack means making deliberate choices about the things you bring with you, but don't get sold a bunch of expensive and unnecessary junk. You can't go wrong with old standbys- nylon convertible pants, synthetic, fast-drying baselayers, etc.
Jeez.... I had a lot to say :-)
