Thank you for the detailed response!! This helps a lot. The light hasn't come on since, so I think I'm fine but as you said will probably replace pre cat o2s at some point in near future anyway.
You may have pending codes, and you will need the OBDFusion app soon enough anyway. Get it and check your long term fuel trims. Also, replace the sensors as JFOJ said if you are over 100k. Not hard, just don't mix up the wires ;)
