I don't think he has a problem with the rear'* compressor working, at least that is not what I attained from reading his post, I am pretty sure he is just looking for spring, and strut recommendations.
I know you already bought the front struts, and the sensa-trac'* are a decent choice for a soft ride, somewhat similar to the OE struts.
The KYB'* would not have been as soft, but they do offer a bit firmer ride, from what I have heard anyway. KYB Part # 334677
For the rear you can go with sensa-trac'* as well if you want to keep with a soft, somewhat factory feel to the ride.
Overall the KYB'* are a bit better product, they cost a little more though.
You do have the automatic leveling system in the rear right?
If so look for the KYB'*, KYB Part # SR1002 should fit your rear.
I don't think the springs wear out that easily, but if you just want to replace them while you are doing the shocks, then I'd go with ACDELCO Part # 45H2107, that springs are 82.00 for the pair.
Don't forget to get it aligned when you are done.
A tip if you have air leveling, and the compressor still works, every year or so I remove the soft EVAP looking line from the compressor that is under the right rear, and I insert the needle from this light machine oil bottle, and give it just a little squirt, it should help prolong the life of the compressor, even though it is supposed to be an oil-less compressor it still helps.
