Hi guys. I am wiring new a 300a service, with a 200a disconnect to a 200a panel and 100a disconnect to a 100a panel. I have wired services before but not with two disconnects like this. I was confident until I went to land E and could not find a lug big enough in the 200a disconnect. It's 2/0 bare AL. Should both bare ground conductors from the load feeder cables be terminated in each disconnect respectively? Also, I have two ground rods and was wondering if they should terminate in the meter base at C or 1 in each disconnect? Also, does having the ground qnd neutral bonded (via bond screw at B and C) create possible objectionable currents? Thanks for any feedback in advance.

E is an EGC and should terminate to the lug A on the left connected directly to the enclosure. If you land the GEC in the meter section you do not need a GEC in each service disconnect. The POCO would need to permit the connection there. The service disconnects require a MBJ in each disconnect. The meter neutral is bonded to the enclosure also. Objectionable current is not an issue.
 
Here for that I would use CDX painted with exterior paint rather than OSB, at minimum you should paint the OSB with exterior paint before mounting that gear.
