I would suggest that you buy an inexpensive OBD scanner (<$50). Then erase all the codes, drive for a few days and then rescan.

Assuming you have the same codes (unlikely) it looks like you need to replace the O2 sensors which is common at about 100K miles and also the MAF sensor. I would start with the MAF to be sure it isn't triggering the O2 sensor errors. Be sure to get the exact right Bosch MAF. Avoid the really cheap deals on eBay which are usually clones or VW sensors which are designed for a smaller engine. It comes as an insert or for a few dollars more with the inline housing. Running with a bad MAF causes the catalytic convertors to overheat (too rich a mixture) resulting in a meltdown.
