I got my JAMMA harness in from jammaboards.net today, and I noticed the two green wires for adding coins seem to be on the same pin. By that, I mean there are two green wires on T and none on 16.

Is this normal? How can I tell which is which?
 
Doesn't matter, they are the same. They're both connected to the Coin 2 input, so both switches will work as a coin input.

Some games like the 60-in-1 will give half-credits from each coin switch (if set to 2-coins per game), but they won't add two half-credits into one full credit if a coin is dropped in each slot. Connecting the same credit wire to each switch solves that issue...
 
Oh, and can I use the extra ground loops I have as a standard ground? The way I'm wiring my Supergun device requires individual video grounds. Would I just take the general video ground and put it on one of the three RGB grounds?
