Hey there, racrane -
First off, you may want to check out our "Featherweights" forum - since you're relatively close to your goal, it might be a great group for you. You might also want to look at the 20-somethings, for those in that age range.
There are also a ton of recipes to explore here, which might be great if you're trying to learn how to cook. My best advice there is to just experiment. The worst that can happen - it's inedible. The best? You get a great new recipe, and the confidence that comes with figuring out your way around the kitchen. There are also some great basic cooking cookbooks on the market - I'm very fond of "How to Cook Everything" by Mark Bittman.
Can't wait to get to know you better!
