1. For the purposes of untainting, do I have to validate every user input value, even though they are all going into a database?

It depends on your schema. If you have text fields that can legitimately contain any old pile of bits, then you can get by without validation. For all other types of fields, bitter experience says to assume the worst. That means validating.
