Poguemahone answered most of your questions, and I agree you should have no problem fitting another derailleur, say Tiagra, to this bike. To do so, all you really need is an 8mm Allen key for the hanger bolt, a 6mm for the cable bolt, and a medium Phillips screwdriver to set limit and tension screws. Oh, and maybe a small pliers to help pull the cable taught.
There is a whole forum on mechanics and repair, and I'm sure you can find details on derailleur setup there.
