Why did you choose 2.5.1p1 instead of 2.5.1p3?

As for ssh and transport, check out this page on the wiki:

Basically, yes, it does tunnel (or transport) the dump through ssh. I
haven't done any benchmarks, but even before I adopted amanda, I was
using ssh for my backup scripts to remote tape drives, becausee I didn't
want possibly sensitive data going over the network in clear. Lots of
weird stuff goes on at universities when all the kids bring their
computers to campus and set up in the dorms, labs, etc.
