The two rear most O2 sensors (the ones closest to the cat fore & aft) are catalyst monitors only and do not have anything to do with the engine operation. Removing the pre-cat sensor will allow for more exhaust flow which should allow the engine to breath better than it is through a clogged cat.

Is there any diagrams or schematics where i can get detailed info on removing that sensor. Im not familliar with what tools will be needed or location of the sensor, will i need to jack the car up and so on. is this relativley easy to accomplish?

Take the whole sensor out and leave the plug empty. This will set a B1S2 code or two, but it will keep the sensor from being messed up any more than it already may be. I would tape up the connector so it doesn't get too dirty and tuck it up safely so it doesn't get burnt on the exhaust.
If you plan on driving a long distance with it like this, you may want to fab up a little deflector to keep the exhaust from damaging anything on the transmission since the port points towards the trans.
