Nope, no nodes connected to something they shouldn't be.  Sorry, you'll have to elaborate, not sure what AO is, as for "normals forward", that sounds like a modelling problem, I hope that's not it, I don't know anything about modelling.
For all materials the transmap is connected to trans and trans edge, diffuse and specular colours are both connected to a node with the tex map.
The hair came from here actually, http://www.renderosity.com/mod/bcs/index.php?ViewProduct=17983 .  It's an oldie but a goodie, just hadn't had the notion to use it much until now.
