So to recap. My balancer's zero marks, driver's side and passenger side, are aligning with their respective timing pointers, but my distributor rotor is pointing very close to plug wire #3. If I were to install the distributor cap and bolt up the battery (I use a disconnect) it'd fire up just fine and run fine...
With your No.1 at TDC compression, the rotor should past no.1 and towards No.3. No.1 has already fired at say 30 BTDC, hence why your rotor now points closer to 3.

Get yourself a TRUE TDC positive stop in place of the spark plug. Find before TDC in one direction, turn backwards to find a bit ATDC. Mark both stops on the balancer. Hopefully you have a 1-2 inch gap to split to find your now true TDC. You can put these marks anywhere you like so your selected timing tab will line up.
