JFP, regarding the leaking injector, is there an easy way to tell which one would be leaking? the fact that I've got both 1128 and 1130 means it would have to be at least one on each bank right?

If you have a leaking injector, it should show up both in your fuel trim values and by looking at the plugs.
I'm not a fan of swapping out O2 sensors unless they check out poorly. They can be tested in place using the Durametric system. These things are too expensive to change out unless they actually need to go.
