There's no limits, FUP or anything else that limits the total throughput of your line.
Traffic management prioritises the traffic so that when you are maxing out the line things like VoIP, gaming and streaming are given higher priority. So thrashing your line to death with P2P downloads won't affect the higher priority traffic.
Router is still the 582n. It's absolutely fine for wired connections, but many people have issues with it's wireless performance.
