If I want to tighten up do I do more sets and reps over time?

Does anyone have any good links or sites that will help (a complete) beginner to all of this?

I feel if I get started into a program it will motivate me to do better for myself (with food).

I adore www.stumptuous.com she's funny and very smart. I think you'll like it.

Also, http://www.bodybuilding.com is good for exercises.

Or read the thread "Questions, Questions....." that Baffled started. Lots of good infor there!
