I have a Bogen/Manfrotto 745B tripod with a 701RC2 head, and the leveling ball’s locking/tension handle has broken. From the parts diagram, it looks like I need the replacement handle assembly (R745,2), but I’m not sure how to remove the broken threaded pieces from the existing assembly and install the new part. What is the usual way to remove the broken stud/bolt from the handle and the ball?

I'm not sure I understand which part you are calling the locking handle.
Disclaimer, I have not seen one of these in person, this is just from the parts list, which are always very handy for repairs (they show how the parts are supposed to go together).
To my eyes, you need to remove two items. First, the broken stud that is left sticking out of the red part of R745,1, and then the matching broken stud sticking out of the ball R555,7.
The first is easy. Put the R745,1 in a vise and use a ViseGrip on the threads and twist.
For the second, I'd take apart the ball and base. Use a socket wrench on R555.05 with the ViseGrip on the broken stud.
Should take 5 minutes or so.

Based on the parts breakdown, the repair is likely replacing the handle assembly and removing the two broken threaded pieces left behind.
What to remove:
- The broken stud still stuck in the red handle assembly piece.
- The matching broken stud stuck in the leveling ball.
Typical approach:
- Clamp the handle piece securely in a vise.
- Use locking pliers/Vise-Grips on the exposed threads of the broken stud and unscrew it.
- For the stud stuck in the ball, disassemble the ball/base enough to access the retaining nut/bolt, then use a socket wrench on the fastener while gripping the broken stud with Vise-Grips.
- Once both broken pieces are out, install the replacement handle assembly and reassemble.
If the stud is badly seized or snapped flush, penetrating oil and careful extraction may help, but the basic method is mechanical removal with a vise, locking pliers, and a socket wrench.
