Shoot RAW for most things except perhaps "snap shots". Download a 1 month trial of Lightroom and start "playing" with processing. LR is fairly easy to learn the basics. Like you, when I first started with DLSR, I just shot JPEG, didn't have a clue what RAW was. Now going back and looking at images that I shot with JPEG 4-5 years ago...I's "Man I wish that I had shot that RAW."
