You might want to take a look at:

Perfect Passwords: http://www.syngress.com/catalog/?pid=3420
It is an excellent resource for helping to decide a password policy length.

It is quick read, and not that expensive ($17 at Amazon):

And the free version of LC5??, maybe we can keep it around for a little
while:

     Your password policy should not be 6.. .but as long as
     deemed appropriate for the risk of the device you are protecting.

     If lmhashes are enabled in a firm, a 6 character password
     is trivial to break/sniff with LC5 [well until Symantec
     sunsets it anyway....]

     Protecting your Windows Network [Johansson/Riley] has an
     excellent chapter on passwords.
