Based on my obconf I have DiceBox theme selected.Based on my gtk-chtheme, I have Shiki-JetBlack selected.Which means I can go into/usr/share/themes/and just delete everything except these two right?I did just that and suddenly my scroll bar's color changed when I re-loaded Firefox and other programs.Why?What other theme am I making use of besides these 2 that I don't know about?
I use : gtk-chtheme & obconf , each one has 1 theme selected, for gtk-2.0 and non-gtk-2.0 areas, but when I delete all other themes.. stuff breaks
gui;openbox;theme;gtk2
You removed some files that are needed. Because you deleted /usr/share/themes/ and the given directory, contains /usr/share/themes/Default and Default contains the gtk-2.0-key and  gtk-3.0 directories.
