Snuggle,
You may want to try a search for digital camera, Olympus or C5050. You will find so many posts about this camera it will scare you. The Olympus line of digital cameras is well supported on this site as well as Digital Diver and TDS.
You have to decide for yourself what you will be using this camera for, because it can be rather pricey to get involved with underwater photography. It is not the camera, it is the housing, the extra batteries, the memory cards, the tray, the strobe, etc. Don't get me wrong you don't have to purchase all of this at once, but in reviewing these posts you will find that somewhere down the road you will purchase most of the equipment listed. It seems that the strobe, arm and possibly the tray can wait. I would give yourself a budget of what you would like to spend, because it will eventually add up. If you are looking for a camera to use a couple of times a year you may not want to invest in such a highly regarded camera for dedicated underwater use. If you are looking for a topside camera you may want to consider size as the C5050 is a camera you will probably want on a neck strap. You can get a pouch to carry this in but there are smaller cameras that are more travel friendly in the 5mp range including an Olympus model.
Good luck in your journey down the digital camera lane.
