To add to sauoq's advice on #1, if you elect to put still-tainted data into a database, make it one which supports tainted data from select. You can untaint now, or when you need it. I like now, bucause I might forget later, and somebody else might not suspect.

On #2, your Validate.pm doesn't untaint anything you can use. You're shifting the argument into a lexical package global and untainting that. The argument variable remains tainted. You can pass your variables by reference to fix that, or else use the (\$) prototype.
