Over 100 metres, certainly heaps of capacity on individual links. At the 
moment, just about every non-RIM link is good for 8 Mbps, and a lot can 
cope with 12 Mbps on ADSL2+. Fewer get 24 Mbps, but some can.

Yes, but note that metro Ethernet is designed to run over a wide variety 
of lower-layer physical connections. Hence, on copper to the home, the 
Ethernet service may use a DSL link (symmetrical preferred).

There's no reason that you could not run up to tens of Mbps on a short 
run - and you get a rollout benefit because you don't need to knock on 
the door for installation.
