Good choice greg. My advice is to play around with it a lot before your trip so you're comfortable with some of the key settings. You don't have to use it in manual mode or anything, but figuring out how to set exposure compensation, or to use the face detecting autofocus and exposure, etc will come in handy and save you from fiddling with the camera when you're out and about.
The 3x zoom you've got will be both a wider on the short end and much longer at the long end than a camera phone and as such much more versatile. The sensor is dramatically larger (on the order of 20x) so it'll take much nicer and cleaner photos in any circumstance. With 24mp you can "zoom" another 2x by cropping and still be left with a 6mp file.
If you have fun with this first "real" camera you'll next want to look at either a telephoto if more zoom is what you want, or a wide/normal fixed lens like Sony's 35mm f1.8.
