Bought a coin 4 years ago.
have address and identifier recorded.
we can move it from coinbase to the wallet, but we DONT KNOW where the wallet is housed or located.
-are we online / offline?
-do we need to be off coinbase when btg drops on the 12th?
- how do we transfer from wallet to coinbase?
-should we just get a wallet on blockchain and put it there.
-how do i access the bth everyone got in september and move it around? if we were on coinbase, did we get that free bth?
sorry for the noobish questions, but i am a n00b
-are we online / offline?
If your wallet is coinbase, as you stated on your next question, then you are "Online" as it is a webwallet.
-do we need to be off coinbase when btg drops on the 12th?
No, it is already too late for that. BTG split has been recorded a month ago, so wherever your bitcoin was at that moment, ( i presume coinbase ) will be where your BTG will be.
BTG snapshot block 491,407 occurring approximately on October 23, 11pm PT (6am UTC)
-should we just get a wallet on blockchain and put it there.
If you mean blockchain.info, then no, i would advise getting a hardware wallet from here,

That fully depends on coinbase, and if they support the fork.
