If I were in your situation id keep the dogs seperated as much as possible, take them out seperately to potty and play. As for your new boarder id give him plenty of space. Just give him a chance to get the lay of the land. Let him make up his mind about you before starting any kind of training.
Right now he doesnt know you and probably doesnt trust you that much. Give it a little time and let him warm up to you and then start with some very simple training for short periods of time with some really good treats.
Work on something like sit, down, stay. A lot of petting and positive reinforcement to let him know he has nothing to fear from you. Remember , he came from a shelter, he was hurt and no doubt scared to death and now hes in a whole new place hes not sure about. Let him hang out for a week or so and dont press the issue. If he doesnt want come to you leave it at that, let him makes the first moves.
I guess thats enough to get you started. Im sure others will have their own ideas but thats what I would do.
