difference between modes

Multimode basically says that you are OK with any of T1.413, G.DMT or G.Lite, so the DSLAM can choose whatever it prefers. If you choose one of the others then the DSLAM will refuse the connection if it doesn't support that mode.

T1.413 and G.DMT are very similar, and support up to the full ADSL speeds of 8M/1M. G.Lite tops out around 4M, at least with my experimentation. So, yes G.Lite shouldn't be used if your DSLAM supports the other protocols. I'd stick with Multimode, since the DSLAM should be configured to use the best mode that it is able to use.

The different modes won't affect latency. Turning off interleave will reduce latency by about 30 ms. But you can't control that from the modem, it is configured at the DSLAM, so the change has to be made by Qwest. There have been other long threads related to this topic.

There is no other QoS mode that would be better than UBR.

Great answer msj I added your reply to the FAQ for future reference:
