Well, by the motherboard chosen I'd guess the OP is looking at the 860 (LGA 1156). If that is the case I'd suggest the ASUS P7P55D-E PRO
($190). This has the IEEE 1394 (Firewire), USB 3.0 and SATA III.
If you're actually getting the 920 (LGA 1366) and just made a mistake I'd suggest the ASUS P6X58D
As for the cables, from a few quick searches I couldn't find anything, but I didn't look exhaustively, so it might just be hiding.
