0.92.x can only spend from older address types. If you picked a more recent address type, 0.92 won't be able to make sense of it. You'd have to update Armory on your offline signer.
First error I get was I must change to "auto" address type that changes the address from a PKG2 (?) to a different type to protect my privacy?
The change address is where your coins go back to. If all the recipients in a transaction are spending to modern address types (SegWit) and there is only one legacy type address (P2PKH), blockchain crawlers will look at the address type of the origin coins, and deduce the legacy type recipient is your change. Armory detects this and recommends you modify the change address type to obfuscate it.
