Best Approach to using multiple threads

I posted this in the C# forum, but this would also apply in the VB world as well. I wanted to get all possible suggestions, not just from a small subset of viewers. It is in regards to what approach I should take with multithreading based on my situation that I described there. If anyone has any ideas or suggestions to my post in the C# forum, please leave your replies there.

I don't consider this cross-posting, but if it is, well, sorry and just fire me. :bigyello:
