Check your mainboard's manual. I know mine's contained a list of possible combinations.

Well, apart of anything, I think upgrading from 16gb to 20gb is pretty nonsense.
Either go for 32gb or leave it.

Depends on what problem you're actually trying to solve. Don't expect miracles from a dual channel config over a single channel one. Internet tells something in range of 0% to 25% faster, depending on the situation. If that's worth spending the money, I don't know.
