darrick,
Fuel Balancing is a symmetrical problem so isn't going to affect longitudinal CofG...
Body fuel is the first to go - always from the Centre Wing Tank, with the Stab transferring first, then the Aux tank if fitted. Then the inboard wing tanks (and reserves) until all wing tanks are equal. Then all wing tanks together (Tank to Engine).
If the Stab tank doesn't transfer you probably have just over 3 hours before you MUST be on the ground.
