I want to do clean re-install

If i try to reinstall Vista will i get a problem when i try to re-register
it and if so what preparation (get new registration?) should i do so it goes
without a problem

Also thinking of buying Win 7 upgrade - could i do clean install straight
from Win 7 upgrade or would i still have to clean install with Vista first?

If you are reinstalling on the same hardware the online activation
should work. If it does not, use the telephone activation procedure.

If you have a valid qualifying licence for Windows 7 you can do a clean
install with Windows 7 upgrade media using
