Faulty O2 sensor

I just finished installing my new O2 sensor and at idle, the voltage cycles like crazy. I knew that they cycled at idle, but I thought that they cycled at a more steady pace. It's almost like the ECU doesn't really know what it wants. Maybe I'm just used to my old O2 sensor, which I think was going out. I've included a copy of a DSMlink log file, so if anyone can give some insight, that would be great.

Also, since I think that my old O2 sensor was going out, will I have to recalibrate my MAF with the new fuel trims.
