Want to level a toon before granting RAF levels

I don't understand how the boosting works. The booster can't be partied with the new toons. Does that mean the toons have to get the kills? That would be a lot more complicated than what I've been doing if I have to control the booster separately and make sure he isn't getting kills.

The booster can be partied with the low level characters and what you said above about having to boost
from account B or C in order to get the RaF bonus is correct. In your case, Account A cannot be the booster
since you did A > B and A > C.
