You definitely want to be using jumbo frames for gig ethernet; I advise using ethernet chipsets with hardware off-load as well, and ensure it's enabled at boot.
I don't understand why you're worried about enabling the jumbo frames though. It doesn't break backwards compatibility. Your 100baseT stuff will continue to function fine.
