Hi,
You can do (b) and (c) with the 'hbond' command from cpptraj: see the
manual for details. Also see tutorial C5 here:
http://ambermd.org/tutorials/#analysis
(a) can also be done, but only in a specific manner (i.e. you will get
details of *every* single solvent-solvent hydrogen bond in your
system) via the 'acceptormask' and 'donormask' keywords. Be aware this
will produce a ton of data.
Hope this helps,
-Dan
