Paul's got it.
The FC200's JPEG quality is pretty good. On an A4 print, you're not going to see a lot of artifacting unless you're really looking (or a professional).
RAW is going to be a little cleaner, but RAW isn't really about increasing resolution. Where RAW really shines is in post-production. You can literally "save" portions of a RAW image, manipulating tonal values and contrast to pull details out of the shot, that would've been lost in JPEG. RAW is also MUCH better for use with the lens correction filters to remove the fisheye of the FC200.
The compromise, of course, is the slower shutter on the FC200, and the fewer images you can fit on your SD card.
When in RAW mode, the FC200 will always save both a JPEG and RAW file for each photo. So set it to RAW and test which one YOU like better. Then you can switch it back if you're fine with the JPEG.
