You're right, you're transmission may very well be on the outs. However, one thing I would replace prior to doing anything too expensive is replace the vehicle speed sensor. This mounts to the tail of the transmission and can cause all sorts of malfeasance, including slow-witted shifts, banging into gear on downshifts, etc.

225 is knock sensor -- you're probably not getting a signal from it. Not a big deal, but not something I'd leave unattended for too long.
177 is Lambda sensor (left) too rich
176, oddly enough is Lambda sensor (left) too lean (maybe your getting readings at both ends of the spectrum)
136 is Lambda sensor (left) mixture lean
