US Airways seat recomendations

I am flying on a couple of US Airways (really America West) next week. The aircraft are A319, A320 and B757 and I am in First.
The question is does anyone know how much leg room the front row has? I have experienced similar seats before and the bulkhead can be very close.
Any recommendations?
Thanks
