Well, for uppercase vs. lowercase (and special characters, come to think of it) I think you'll have to check the ascii value of each non-numeric character in the password string. That is if there isn't some sort of IsUpperCase() or IsLowerCase() functions already in existence... in fact you may want to write those functions.
I'd probably scan the password a character at a time running the tests on each one and keeping a tally of each success. At least one success for each test, and the password is good right? (as long as it meets length and history requirements, of course). > 3.

Three records for each user. That kind of thing. Well, those are my thoughts. Hope they help.
