Every digital camaras works pretty much the same way. The quality of the output of digital camara is determined by its megapixels(it should be notified on your camara). The higher the pixels better the quality, at the same time lens also play the vital part in it's output, for developing at photo-lab or printer try adjusting your resulation upto the highest. If you just want for email or website - adjust lower resulation.
Alternatively, photos you took on high resulation can be cut, trim and manipulate to your need by the photo software that came with your camera. But photos taken on low resulation(email and website) aren't good enough for printing. That's why it's always good idea to take photos to camara's full resulation and manipulate to your need later on.
Digital camaras use memory cards instead of films, so whatever you take are stored on memory cards. You simply take that card to photolab to print. The number of photos and videos(didital camaras are also equipped with video capturing function) can store is determine by the capacity of memory card. The common ones now a days are 512mb, 1gb and 2gb.
Digital camaras come with LCD pannel where you can see your photos before and after you take. If you aren't happy with your photo simply delete it and re-take until you are satisfied.
Turning off LCD and taking photo through view finder saves battery.
