It sounds like you are on the right track. I would suggest also 2 things:
1. install the charge controller as close to the batteries as possible to minimize voltage drop between them (unless the controller includes remote voltage sensing). This will allow faster charging.
2. try to get a charge controller with temperature compensation. My low-cost PWM controller has it. Colder batteries need to be charged at higher voltages - having the charge controller adjust voltage with temperature automatically is real nice.
