This question is very broad. It's also a very tricky area to master, network programmers are pretty sought after in the industry with a matching pay, which kinda indicates it's a 'non-solved' area. Are there books out there, yes, plenty. Are there good books out there, no doubt. Are there books out there that will answer your questions?...I don't think so. They might have solutions that work in some situations or pointers on what to look for, but almost all your questions are game dependent....this is an area where you'll really have to work a lot on your own, it's so seemingly trivial and it can go wrong in so many (uncontrolled) ways.
