You have a profile of 7.2meg, which is the max you can download with overheads. Real throughput can be maximum just over 6500Kbps which is then dependant on source speed, load and throttling of BT.
I don't think you will be able to do advanced QoS on the home hub. I haven't seen the interface, but I doubt it will have that option. If you wish you can get a Linux box plugged into the router, then have a switch from the PC and a WAP on that. With this you will be able to do advanced QoS of clients. (Don't ask me how though!)
