The Bladebound.

First, this archetype forbids you of a familiar, but can I still have an Arcane Bond from the Wizard class? Since it specifies that you are forbidden of a familiar (specific) and not an arcane bond, since the arcane bond is not an intelligent item (and the familiar is, not an intelligent item, but intelligent nonetheless)
Second question, this bladebond allows me to have an enhancement bonus on the weapon depending on my level, if I am lvl 6 for example and I have a +2 enhancement bonus, can I have for example a Keen Longsword +1 instead of a Longsword +2???
My main problem with these rules is that this text does not specify my questions.
