Using a Canon EOS 300D, which I believe is almost the same. (older version)
I started for a long while using it in point and shoot mode with jpg, then moved to my own setting in the AV M settings etc, once I had mastered the camera, in all the above I then started with doing a group of shots in both jpg and raw. played around with them to see exactly the difference I could make with RAW shots, found the Pixemantic package was excellent.
Last 1000 shot's have all been in RAW, I now prefer it. I'm not a pro, just a very keen amateur. Biggest problem with RAW is you need a lot of storage space for the RAW and the product you make from it...
