A monk eventually gains the ability to bypass DR lawful and admantine by spending a ki point. However, a monk does not gain any inherent ability to bypass good or evil DR, so no the monks fists do not bypass the DR. I don't not think an aligned weapon counts as being able to overcome DR, that is what the Holy weapon enchant is for. If the weapon is intended to bypass that alignment it would have the enchant on it.
