Books?  Best start is Busby's 1977 reference _Manned Submersibles_.  In
most large libraries, and possible still available through the U.S.
Government (it was
published by the Hysrographer of the Navy).  Busby has the basics of
design
covered, including most of the math.   It's all about small research
submersibles, but there's a section of photos of homebuilts.

Most of what's written is military in perspective.   I have _Submarine
Design Concepts_, by Boucher and Lydill (I think I got the authors names
spelled correctly: the book is on the table by my bed now, because it's
my 'relaxing before sleep' book).   This is focussed on larger ships, but
contains some insights quite valuable for little subs, too.

Software is going to be a bit more challenging.   Do any of the available
software
packages permit test of a submerged submarine?   I don't know.  (I do
know that Carlson's Hull Designer program will crash when the waterline
is placed above
what the program thinks is the gunwale.) 

Edmund Scientific, Herbach & Rademan and Small Parts Inc can provide some

equipment and guidance.
