gem help install
see for --http-proxy option which accepts an URI or use HTTP_PROXY environment variable:
gem install foo --http-proxy=http://user:pass@server:port/
Hope that helps,
have you tried the Rails Installer(railsinstaller.com)?
I have found this is the easiest way to get rails up and running on windows.

I dont think you want to install ruby 1.8.7 with rails 3.0.0.... i was never able to get everything working in windows reliably so i went with ubuntu on my windows box and have good success with that.. But one problem i had wad trying to use the older ruby with the newer rails.... I did find something eventually about the mix on google but dont remember the link... Good luck
I was able to get ROR installed on windows XP and I felt it was stable. I wrote about it here.
Hope that helps
