as i said, try tortoise git. msysgit is just the underlying git environment, and is pretty much the same as git on linux. tortoise git is the GUI front end and windows integration bit that makes it nice and usable.

cmd/powershell are horrible, so just install cygwin and ignore them. it gives you a fully functional bash shell with a package manager and the majority of the common Linux utilities and plays nice with windows CLI programs.

I cannot comment on Eclipse, but with msysgit + tortoise git, git pretty much just works in windows and integrates so well even our non technical staff (designers, QA etc) use it without any issues.
