You don't have to shoot RAW right now. It isn't like JPEGs are all going to be a worthless waste of time. If a JPEG comes out looking pretty darn good, I'm not sure there's a whole lot more where RAW will help - or if it would be worth the effort.
Actually, to start, I'd just shoot JPEG until you get the hang of using the camera and look at your shots using something like Irfanview. You'll be more able to quickly see where you're going wrong, or right. You're not going to be able to truly judge your photos by looking at them on the LCD screen.
I'm sorry but I disagree - strongly. If you just want the camera's automated result, this may be good advice.
But remember Ansel Adams' analogy of the negative being the merely the written composition and the print the performance. Put in a digital context, that means the image file is just the beginning of a realized image.
OP, JPEG is just not as flexible as RAW and having a bunch of early JPEGs that you regret making because your skills are growing but the JPEG won't let you reach your personal vision for an image is not a good position to find yourself in. Shoot RAW. If you don't want to process RAWs right now, shoot RAW+JPEG and save the RAWs for when you have a better idea what you want to do. But don't handicap yourself with a buch of JPEGs that you will later regret.
