RAW vs. JPG? I recommend you investigate it further then decide if it is right for you. There are a lot of articles that cover your exact inquiry.
If you need the functionality I say go for it. RAW has a lot of capability.
If you don't need it or won't be able to take advantage of RAW then shoot jpg. If you simply adjust brightness and resize then you may want to shoot jpg. Just don't keep saving your working images as jpg, use PS, GIMP or tiff format.
One thing to keep in mind is if you shoot RAW you will probably have to convert any images you want to use on a web site, send in email, instant message, mobile message, etc-. RAW files can be big and when you gather, oh say 40 or 50 gigs worth you have to do something with them.
