Best thing is keybinding your normal spells instead of using action bars for everything. Reaction times are faster with keybind because you are working off memory instead of hunting for a spell on an action bar.
Generally I only use bars for displaying cooldowns so I can quickly reference them. A different bar mod you may want to check out is Macaroon. It allows you to write macros and keybind them right on the bar instead of using multiple interface panes to try and do that.
