I would keep packet sizes under 1500 the least amount of packet overhead and greatest equipment compatability.
It's probobly not necessary to have a bunch of ports open just to talk to other peers, because you get the remote IP address each time you receive a packet. I suppose if you want to use your router to monitor or control ports it might be handy to have ports open for each peer.
My preference would be to send important position updates 10 times a second, and others less. Some game designers like to assign priorities to packets, and adjust the prioriries based on such things as TARGETED, RANGE, INVIEW..
Sending those packets first.
The whole network game protocol thing can be complex and even the pro's don't get it right all the time. Take your time and enjoy.
