To monitor interface throughput, I often use nload. It shows an ASCII
graph and cur/max/avg bandwith usage.

This heavily depends on the connection to your house, I think.
Everything under 100ms is acceptable for me.

pppd should handle things like MTU and setting up routes. Latency and
packet loss are basically out of your control (until you have a gross
misconfiguration on your side).
