As far as serpentine belt size, pick the length for your vehicle that would be correct for the same configuration "sans" one ancillary unit...like the A/C. I believe they are sold that way.
Curious as to how you managed to procure the correct bearings for that pump?
One of the big issues with why we have to go to rebuilt units is that the bearings are a metric-size, impossible-to-find component...otherwise, most of us would have just cracked open the air pump housing and done the swap ourselves!
Share us your secret...
BTW, the sole purpose of the air pump is to spool up the optimum emission efficiency more rapidly. This is most important in Europe, where laws require emissions tests to be performed within 60 seconds of starting the engine.
Here in the US, it's not that critical, so the pump could be deleted from the system entirely.
