http-status-code-301

I have a few messy old URLs like...

http://www.example.com/bunch.of/unneeded/crap?opendocument&part=1

http://www.example.com/bunch.of/unneeded/crap?opendocument&part=2

...that I want to redirect to the newer, cleaner form...

http://www.example.com/page.php/welcome

http://www.example.com/page.php/prices

I understand I can redirect one page to another with a simple redirect i.e.

Redirect 301 /bunch.of/unneeded/crap http://www.example.com/page.php

But the source page doesn't change, only it's GET vars. I can't figure out how to base the redirect on the value of these GET variables. Can anybody help pls!? I'm fairly handy with the old regexes so I can have a pop at using mod-rewrite if I have to but I'm not clear on the syntax for rewriting GET vars and I'd prefer to avoid the performance hit and use the cleaner Redirect directive. Is there a way? and if not can anyone clue me in as to the right mod-rewrite syntax pls?

Cheers,

Roger.
