Couple things I noticed:
You cannot have 2 feeders to the same structure; just give the garage door opener its own 15 amp circuit in the subpanel, sounds like you should have enough spare spaces. You could even tie it in with some primary lighting (or exterior lights).
The ground rod wire running through conduit must be properly bonded to each end of the conduit, just simply running the wire through the conduit is a no-no. Personally I'd just run it inside the wall and out through the same hole as your LB (just run it right next to it) and then caulk the hole.
I believe to be code compliant you need 2 8' ground rods at your detached structure.
The rule of 6 doesn't apply after you install a disconnect. Code minimum for a disconnect at your detached structure is 60 amps (no matter what the supply is).
How far does your feeder run inside the garage? Does it come in and go directly to the panel within a couple feet? If your feeder runs further than about 5 feet inside the detached structure, you will probably need a separate disconnect outside or nearest the point it enters the building.
