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
