There's a really great book from the CAEA here in Canada called 'Stage Managing the Arts in Canada' it may be slightly out of date (as you should always have extra floppy disks around) but that would be a great book for you to check out to get some tips, as it is actually used as a reference in both the Stage Managing the arts conferences as well as University programs. Other than that it would just be nailing down/outlining the specifics of your theatre, ie. where important things are, who to call for maintenance issues -- all the quirks that only someone working there for years would know.
