You can use both the AEM pulleys (the alternator and the power steering) with the JRSC. The correct belt numbers for using the AEM pulleys with the JRSC are in the above posts, but to once again summarize:
power steering: 4pk1065 (comes with AEM pulley kit, don't know offhand what the Gatorback number is, although I meant to get one for this belt)
alternator/ac: 6PK1970 (Gatorback number 4060775)
And for the nay sayers who believe one or the other AEM pulleys will not work with the JRSC because their installer said so for whatever reason, here is a pic that proves they work just fine with the JRSC:
