1) Yes, I did. It's not exactly optimal, but we are going to be crafting a lot soon anyway, since we owe archive, it makes sense to put all the crafting actions together
2) SGI is a training booster, or should be. Those are best bought as early as possible. Ideally we should be able to pawn off school onto a clone, and, if not, put clones onto learning stuff in the courts. IDU synergies well with Lydia's Companions of the Hunter.
3) Yes, Whampires can be exorcised using the same rules as turning fomori human. It's one of the possible options for handling Mutt, not the only option. If he wants out, I say we provide him an option to get out. He is suffering from a horrible medical condition, after all.
