Switching to Uverse?

[sportscrazed2]

I'm switching to uverse in a couple days and haven't been able to find any official documentation on how to setup a third party router. I have a pretty complicated network setup. My main router is connected to the dsl modem in the living room and is connected via pppoe. I run a cable to a powerline adapter and have a second AP connected to the powerline adapter and my gaming consoles connected to the AP wired. I also have a third router acting as a bridge for my desktop that is too inconvenient to wire up. Any advice on how to properly configure uverse?
