If you don't have any loops in the topology, you shouldn't worry about where the RB is, as you won't have any blocked links. Anyways it is always a good thing to manually control the RB election by tuning bridge priorities.
Spanning tree convergence comes into place just when a topology change happens, but won't impact on the overall performance on the network if it is stable, and has nothing to to with where the L3 is (at least in your example). Convergence times depends on several factors: which STP version are you using? Did you configure all of your access ports as portfast? Did you do any tunings on the spanning-tree network diameter (which is a macro to tune STP timers). And, just to mention others: do you have DTP enabled? do you use autonegotiation? L2 convergence could take pages and pages....
