Allow me to second MrFotoFool's position.
From what you've written, I would recommend you stay away from RAW until you've really nailed composition, exposure, and white balance.
I disagree with a couple of points.
First, learning to develop RAW images and learning composition, exposure, etc. are not mutually exclusive. The OP can do both, in parallel.
Second, it is less time consuming from a PP perspective to shoot jpg and print or post on the web but its not that much more time consuming to bring RAW into DPP or into Lightroom with presets. On the other hand, your ability to do PP if you want to is much more limited with jpg. In particular, you can't expose to the right with jpg and bring it back, like you can with RAW.
To the OP:
Yes, I only shoot RAW. IMO, RAW and jpg is truly a waste of space and I very rarely need to send a jpg off so quickly that I can't run it through DPP or LR.
And yes, I generally use the same settings, again, assuming my exposure is good. About the only thing I do in DPP, if my exposure is good, is adjust the sharpness. On the other hand, if I'm shooting against a snowy background and end up underexposed or conversely shooting a dark subject (like a moose) and end up overexposed, its nice to have the ability to adjust each photo individually.
Like others have mentioned, check out the tutorials for whatever PP software you're using.
Hope that helps...
