MegapixelGet the highest you can afford, but try to get at least a 3 megapixel camera.
Memory TypeI'd recommend getting a camera that uses Compact Flash, and shy away from those that only use SmartMedia. On what brand of CF Card to purchase, I would only recommend getting Lexar Media cards. Decide how big you want it, then get an 8x,12x, or 16x, depending on what your budget is. In my own personal experience, my 8x Lexar 128MB card is at least twice as fast as the Sandisk 128MB card that it replaced. I can't stress enough how nice it is to have a fast CF card!
Cache memoryThis is something I neglected to check out thoroughly when I purchased my Nikon cameras, but fortunately, they work just fine for the type of pictures I take. If you plan on taking several quick snaps of a moving target, this is something you'll want to check out. Most cameras will allow you to take a few quick snaps, but after that you'll have to wait while the pictures are saved to the memory card - the speed of your memory card (as above 8x,12x,16x) will be a factor in this too.
Zoom capabilitiesFigure out what the camera's built-in
optical zoom capabilities are, and find out what options the camera has for external Zoom / telephoto lenses. Ignore
digital zoom capabilities. Digital zoom sucks, and you won't want to use it if you want quality pictures.
BatteriesIf the camera you decide on uses a battery pack, find out what the charge life is, and probably work another battery into your final price. If it uses AA's, get yourself two or three sets of NiMH rechargeables and a quick charger.
Other things to look at are construction, LCD screen size, ease of use in auto-mode, plenty of options in manual mode (if you want to be able to tweak stuff yourself - shutter speed/white balance/etc), and make sure it allows for screw on lenses/filters and get a UV filter right off the bat. A UV filter won't affect the picture, but will act as a protector for your camera lense.
I'm definitely an amatuer when it comes to photography, and I own the Nikon CoolPix 995 and previously owned the 990. It's worked great for me in auto mode, and is even better now that I'm starting to learn/play with the manual settings. I've had several pictures developed(printed) by online digital film places like shutterfly.com and they look as good as 35mm. Definitely look at what's out there currently, and go to a good camera shop so you can play around with the cameras and see what you like. When you know what you want, buy it online. Search places like My Simon* for good prices and places like amazing-bargains.com for coupons for online stores and hopefully you'll be able to find a nice combination of good base price plus a good % off coupon.
Well, I hope that info helps. That's pretty much all the stuff I researched/had to deal with when I made my two camera purchases. Good luck!

*When looking at camera prices on My Simon, beware the
too good to be true deals. They are. Generally you'll either get the ol' bait and swich or some will even try to sell you a camera without any accessories (ie: memory card/battery/etc) and bump up the price selling them to you. I got a great price from
MP Superstore, and they didn't harass me to buy accessories.
