Action bar questions

[GhostNova]

I have 3 actions bar set up in my Totorox Dead theme, but the 3rd row on the bottom has my skills, but it's not usable and I can't click on any of the skills, how do I fix this problem? Also, is there a way to maybe make my chat box a bit bigger? Please and thank you. Also, how do I display my Exp bar on an alt character?
