New to Anonymity Proxy, Can Anyone Help Me Out?

[DigDogg]

I'm just learning of proxy servers.  The anonymity proxy seem to be the one's to hook
up to.  My questions:  
1) What things should I definatly know about proxy?
2) Where can I get the best lists (here it looks like)?
3) Once I use a certain proxy server, will I ever need to change it.  And any other info you kind people think I should know, let me know!

2) http://forum.my-proxy.com and

3) Yes, because proxies always die quickly (usually in one day)
