1. There may be a very slight slowdown, although you probably wont notice it.
2. I'm used to Linux, so I dont worry to much about that
3. I'd recommend setting up a linux computer to share the internet connection etc. Run the squid proxy server on the linux machine. There are many ways to set something up so they can only view websites you allow them to. There are also some nice mods for quid that will block pretty much everything unsuitable for kids.
4. Not that I know of, yet. There probably is somewhere.
5. You can set up rules with the squid proxy server to only allow connection to the internet from certain machines during a certain time of day.
6. There are some out there, but I don't know of any.
I run squid on a pc at my house which is only 200mhz, with a 4gig harddrive.
If you want to go the squid way heres a couple links to help you:
