Car running rich - O2 sensors?

Another post got me thinking about this. I am pretty sure that my car is running rich since I added the y-pipe and intake, because:
a. I can smell it
b. It hesitates a little when I floor it from a standing start, and
c. There's black residue in the exhaust tip.
I think it's the front 2 O2 sensors (the rear is relatively new), since they have 121k miles on them. Am I right? What else would cause this? I disconnected the battery to reset the computer, and that helped but did not cure the problem.
BTW, http://www.nissanparts.cc has the O2 sensors for about $60 each. Anybody know what part numbers I need?
