It's always worth a try. The less crowded an IRQ the better I guess.

Yes. You can disable the FireWire driver by blacklisting it in 
/etc/modprobe.d or disable it on the cli with sudo modprobe -r 
firewire_ohci (or running that command as root). You could even try 
unbinding the USB port and if you could move your nvidia GPU to another 
slot it would almost free up IRQ 16.
