Did our S-IVBs used on the Saturn IB for Skylab have the attitude
control RCS packs?

Yes -- for roll control, stabilization during separation, and deorbit
attitude control.

I thought we discussed this once and they deleted them due to no need to
extract a LM from it.

I suspect you're mixing this issue up with the discussion of the SLA
panels. They were retained, rather than jettisoned, on the Skylab
launches because there was no payload that they might obstruct, and there
was a desire to minimize debris. (On ASTP, the presence of the Docking
Module trumped the debris issue, and they were again jettisoned.)
