haha ... off point is my specialty.
As for your questions:
http://pbskids.org/ is the site I was referring to. There are a few for pbs but some are pay for sites. This one is free.
Concerns about getting into my files: I'm lucky in that my DH is a programmer and works for a microprocessing company which means we have tons of computers in this house. When DD started to show interest in the computer; DH set up a separate computer in the living room for her. I'm sure computers will be a major part of DD's life but we concluded a long time ago that she will never have one in her room. And we are advanced in the technology industry and know how to lock things down and eliminate most of the dangers but even then we won't allow a computer in her bedroom. (See ... told you ... queen of off point!)
Mouse: She started with a smaller laptop model which fits their hands a lot better than the big desktop kind, but now she has a big wireless one and has no problems using it. Some people use trackballs for the young ones to start with but having used both types myself, I find track balls to be a mirror of mouses and you have to retrain your hand when using the mouse.
