Unit Testing - best practice for multiple runs

I've never worked in a TDD shop and thus don't have a lot of experience with or people to go to for unit testing questions so I figured I'd ask all of you. I want to find the best way (least code/effort) to run a bunch of different tests with changing data and environment.

For example right now I have a test:

public void TestI32(Type inspectable, MemberInfo member) { Assert... }

I'd like to run this test with different arguments and have each test show up separately in a test result window or report.

I'd also like to repeat the tests from a 32bit and 64bit process. I recently discovered a bug that only showed up in unit tests and only because mstest runs tests under a 32bit process...

Also, I'm not tied to using mstest but visual studio Integration would be nice. In the future, easy integration with a build script / continuous integration would be nice too.
