Congrats he is a handsome guy.. I'm no expert by any means, and everyone has a variation on when to handle for the 1st time.. After x amount of weeks after x amount of feedings. Personally I wait until they have 2 feedings, it could be 2 weeks it could be longer. Being active all the time doesn't mean they are comfortable, as he just arrived he is still adjusting to his new home.. A happy adjusted BP is usually one you never see.
As for a bath I've never had to bathe one on arrival. You could rinse him in warm water and dawn dish soap..
As for feeding offer him a meal on feeding day based on the schedule the breeder had him on. If he doesn't take it offer again in 5-7 days.
Good luck..
