See Linux-Virtual-Sever if money is an issue.. very nice.

Yes, as long as the name of the proxy is the same the browser will
assume it is the same proxy, even if the IP differs from time to
time.. (this is the name the browser is told to contact, before being
DNS resolved).

Authentication in combination with multiple proxies is only a problem
if you are using proxy.pac files to distribute the users on the
proxies.

Depends on the browser. Most don't.
