I think I'd wait a week on question one if you are wanting to do this transfer soon.. you don't want to get lost in the shuffle. I'd maybe wait a little longer if you're planning on this taking a while, because you don't want to get on anyone's nerves by bugging them to death.
On question 2, definitely call the guy you've been in contact. You'd MUCH rather do things correctly than risk getting on anyone's nerves here because (in my experience) might confuse someone by applying to too many jobs and that could get ugly. I have NEVER regretted picking up the phone to talk to a human (and I'm pretty shy about the phone).
