@LordOTC -

That's a lot of questions! It is usually best to keep the thread on-topic... your extra questions don't really belong in this particular thread.

i'm working on a university project to create the best cheap alternative for gaming over WiFi on your home network,

Please don't take this the wrong way, but with your stated goal, my guess is that you should be learning about all of these things. Rather than just following a few guides and/or asking generic questions for people to tell you 'use this' or 'do that,' I think you'll be much better served by searching the web and these forums for all the various options and figuring out what will work best in your specific situation and learning how to implement everything step-by-step. Exploring and researching will help you understand not just how to do these things, but also why they are done in certain ways, how certain technologies/packages/configuration options work, and which ones are better for your application than others.

The community here is happy to help and we can give you guidance when things are broken or when you need pointers or information about some of the details. But, especially since this is a project for school, I don't think it makes sense for us to kind of do it for you, if you know what I mean. Please feel free to open new threads for new topics as you make progress and need help -- we have a lot of knowledgable people here totally willing and able lend a hand.
