Just make sure you spend the $20 for an atsg manual and you'll do fine. You need to be a little creative with the clutch packs, since no home user actually owns the tools that they call out. Usually a press or some all thread and scrap steel are enough to make your own compressors.
I've done a 904, Th400's, aw4 and C6. None of them have required tools that couldn't be jury rigged with what was laying around. (Except for an accurate torque wrench for soing the band adjustments)
