Sounds like the Audiophile card would be OK. 4 inputs, right? Give you more flexibility later. You just need two inputs to do what you're describing. After you determine what basic type of setup you want, just make sure all the hardware and software is compatible. You might want to get a package deal from a retailer you trust.
No, wait... the Audiophile just has two audio channels of input, not 4. But that's enough for what you want to do. Haven't used or heard one, so don't know how it compares in quality of sound with others in that price range.
