Better off buying a new one. Nobody offers service on these things, and if they did, you could buy a new one for what they would charge.
I have an older Olympus C-5500, 5.1mp, 5x zoom. It has the sport setting and all of the other options, but what I like is the ability to turn off the screen and just use the viewfinder. Call me old school, (I am), but it saves a lot of battery life and the ambiant light conditions don't effect your framing a shot. Bright sunlight or darker indoor situations are hard for me to see on that little screen.
Don't worry about mega pixels, anything over 4mp will do the job. All the rest is marketing. The Cannon or Nikon SLR digital units go for $500/600. They weigh a little more, and won't fit in your pocket, but they take great pics. Buy an extra set of batteries, some cameras will just lock up without warning when they die. The NiCad ones make for a good back up plan, but the Lithium ones will last longer.
Print making is all about the printer and how much you want to spend on ink. I have a new HP all-in-one, and I can put my media card into the printer and print from there, or download to my hard drive from the printer.
All of the major brands are rated high by Consumers Report, so it's mostly personal preference. Best tip for good photos: Be a little more patient in setting up the shot, and keep the sun at your back whenever possible.
Good luck.
