I installed Windows 7 a few days ago, but unfortunately I can't offer much assistance since my install was swift and pain free and so far I'm liking Windows 7 more than XP. Your file view problem however can be solved by setting the view that you want in the current folder you have open then clicking:
organise > folder and search options > view > apply to all
I didn't like the details view so I changed all files to small icons.
