You're describing "faceted navigation" which can rapidly grow the number of URLs available on your domain. You often need a lot of backlinks before Google will even think about a deep indexing like that. I even know a large site with a PR8 home page that gave up on getting all their faceted URLs indexed.
IMO you are better off aiming to get some higher level "hub pages" indexed.
