If I need to keep moving while I need to do something with directionals, I just use my right thumb on the left thumbstick instead. You shouldn't need to be moving that long between clicking whatever is on that side and then moving your left thumb back.

I usually keep all my cool downs on the left side, or combos that I need to use less often.

As for Shatter, I don't PVP much anymore, but I just use the mouse pad to target crystals since they don't move. Also, when you're trying to target something make sure your camera and character are facing it, you'll be more likely to target it.

I can't remember what I have my filters set to and the maint is going, but you should be able to prioritize things pretty easily in the menus.
