Hi treadmore, welcome to the forums
I wouldnt worry too much about still being "capped" to 2Mbps, it seems to be quite a common feature that the BT profile seems to stay at 2Mbps for around the first 3 days, regardless of what speed you are syncing at.
For 10 days, kit at the exchange will monitor your connection to find the most appropriate speed for your connection, so hopefully you should start to see this increasing over the next few days, after which time it should find your MSR (maximum stable rate).
Probably one of the best things you can do is keep your router switched on over the next 10 days without disconnecting it.

Local is your downstream rate whereas remote is upstream...
Downstream relates to how fast you can receive data.
Therefore your important figures are local line attenuation and local SNR margin.
The SNR margin seems to be coping quite well at a sync speed of 8128, so its looking ok so far.
Continue to monitor.. the problems you dont want to see are lots of CRC and HEC errors.
Im not sure where they are in the web interface on the netgear, but in case you cant find them they should be able to be accessed via the telnet commands
$get dsl stats cntrs
and
$get dsl stats curr
Hope this helps
