I wouldn't do an O2 unless it's throwing a code.
Up tire pressure and when it's time, get some LRR tired. That's the low hanging fruit. Some underbody panels will help but not as much as driving a little slower.

I've always been under the impression that upstream O2's should be replaced every 20K as a maintenance item. Downstream O2's I just bypass if they throw a code, no emissions inspections where I am, and this van is our only vehicle with a functioning catalytic converter.
I did come back to say I found out they were coil on plug, I didn't know that yet when I first posted: I haven't dug into this van much as we just finally broke 50 degrees in sunlight yesterday up here.
