Thank for this guide. I'd also recommend using the add-on KeyPad and ORing. Combined with effective keybinding, it makes for smoother gameplay and a cleaner UI. I use ORing to bind professions, food, portals, stances, to Alt-modified keys. Typically for things OOC since I, too, find it difficult to use anything other than ALT-T in combat. But this will clear up a lot of screen space.
