What are the differences in the firewire ports (regular, 400, 800) and what would I need to connect to each?
"Regular" FireWire is FireWire 400; they are one and the same.
FireWire 800 uses a completely diffeent connector. You need a third-party FireWire 800->400 adapter to use your existing hard drive on a FireWire 800 port.
