Heh, I'm no photographer, at least not professionally! I actually don't have any special lenses with my camera - a Panasonic DMC-FZ5 which is a fixed lens.
It has 12x optical zoom and I believe 5 megapixels.
The higher the optical zoom number, the farther you can zoom in. That means you can zoom in on objects that are really far away. For me, I'm a nut about taking pictures of skyline views from far away. I've been able to photograph 10 story buildings that are 12 miles away. Sometimes there will be a view where I know or think there will be a view of downtown a building, or some far away interesting object. Sometimes they're so far away that you can't see them with the naked eye. So I'll set up the camera on the tripod and let it do its magic. That's always fun.
The higher the megapixel number the better you'll be able to blow up your photos without them seeming pixelated. Let's say you take a portrait photo of someone and want to blow up the image for a large portrait. You'll be able to do that without it being pixelated. If you've ever saved a photo off the internet and then taken it in a photo viewer program or photo editing program and zoomed in/enlarged the view, you know what I'm talking about. It becomes pixelated and distorted. With a high megapixel number you could blow up your skyline images into full sized posters if you wanted.
Here's the Wikipedia page on pixelation in photos.

About batteries, definitely look for a camera that has a rechargeable battery, other than say AA or AAA batteries. Digital cameras eat batteries like crazy. My camera battery is about an inch square and can be taken out of the camera and charged in any wall outlet. It takes 2 hours to charge which is really reasonable considering some take up to 20 hours. Digital cameras are notorious for sucking battery life. This is especially true if you use your flash a lot or if you're doing night photography where the shutter stays open a long time. Most digital cameras now days also have video recording capability, and that also eats through batteries.

That's true with just about any camera - night photos. Really, unless you have a tripod, or a convenient post or something to set the camera on, the images will blur. Otherwise, you have to have Monk-like steadiness to keep the camera from blurring/moving.
