I'll take a stab at part of it.
Steep grains 160-180* for 20 minutes
Bring to a boil and add can and dry malt
Stir constantly until it begins boiling again
Add bittering hops and boil 55 minutes
Add finishing hops and boil 5 minutes
I'm just not sure when/how to add the Gypsum and moss Perhaps add Gypsum with the malt and steep the moss with the grains???
This is all an uneducated guess from another beginner though.
Just saw this thread on moss http://www.homebrewtalk.com/showthread.php?t=11579
