Just making sure-Reg Q says it only applies to state member banks and national banks (and a few others) but not state non-member banks, right? I read that and just wanted to make sure that somewhere else state non-memeber banks were not later included in the coverage.

No, Reg Q applies to nonmember banks, per the Banking Act of 1935 - FDIC Insurance.

Take a look at FDIC Rules 12 CFR Part 329. You will see that it is virtually identical to Regulation Q, and applies to state non-member insured banks.
