I say take and either keep or burn the last 2 northern mansa cities, as has been said they'll cause culture issues with captured English cities. Bismarck isn't a zealot so you'll still get a -1 for your English war, but who cares how the next person in line to be crushed under your heel feels? You could do a shock and awe raid to attempt to vassalize monty, but from my experience he refuses vassalization till he has 2 or 3 cities left with tiny garrisons, and you don't want to pay maint for cities over on his continent.
I predict that the general consensus will be take those last 2 northern malinese cities then continue your war against the English. Now you can use Montezuma for your GM economy as it's likely that you will need to kill everyone off on your continent. Another thought, depending on leader personalities you could try to vassalize all of the remaining civs for conquest, but Winnie and Monty are tough nuts to crack as far as vassalizing goes.
Oh, assuming that monty dosn't share a religion with you i'd expect a giant stack of midevil era units popping up in your core area sooner or later, be ready for it. EDIT: Oh, looking back on the post monty has no religion. Send a galley over to convert him ASAP before some crappy religion spreads to him. Keeping him happy isn't nessicary to your survival but it will keep him from making a pest of himself while you're conquering the world.
