As long as it's for storage and not for use as a boot drive, OP can partition with GUID and use all 3 TBs on each drive. PowerPC Macs require the Apple Partition Map for booting, though. The boot volume, therefore, is limited to 2.2TB.

Yes. You can have a 2TB boot drive (APM) and a 3TB data/storage drive (GUID). Since we're not talking IDE/PATA, it's not really a "slave" drive. There is no master-slave relationship between SATA drives.
Also, with the addition of a SATA card, you can add more drives if 5TB is not sufficient for your needs.
