Are there any Mods that people have found useful for targetting and target tracking in Arenas? The best case I can think of would be a mod that dynamically fills an "enemy group" frame with the other team as you target them each match and then allows you to bind hotkeys for going back to targets, or at least click target without having to find the person on the arena floor.

Right now I use Bongos and X-Perl and attempt to set my secondary target as a focus and then switch off to the primary kill target so I can quickly switch back. But unless I get time to mouse over some of the other team at the start I often wind up with a choice between tabbing through targets (painfully slow, and especially bad if they have lots of pets) or trying to pick someone out with my mouse (our team has 3 Tauren so that is dicey as well to try to target around our big ass models).

Right now I feel like we lose about 1 match in 5 that we could win by improving reaction time on target selection from 1st target to 2nd target. We are a burst DPS Team with an MS Warrior, Mage, Feral Druid, Shaman, Paly, and if we get a good assist train going we usually have a 3-5 second kill time on the first clothie, but can still lose a match if they get our Shaman down before we get into the 2nd target.

Anyone have any input for Mods? Or even technique for targetting I may be neglecting?

Sounds like you're looking for arenamaster (browse http://files.wowace.com/)
Makes a little frame with enemy players in the arena + target icon.

Thanks, that sounds perfect from the description.

There used to be a mod called BGAssist that sorted targets in range according to how many people on your team were targeting them. I don't think it works anymore because it programmatically alters a frame during combat.

Yeah, it appears you can't alter frames in combat. I have been looking into these Mods this week and I found one I like better than ArenaMaster called Arena Live Frames.

Arena Live Frames lets us target off of clicking the entry in the frame rather than a target icon off to the side of the frame which isn't lined up precisely with the name entry (I don't know if this is a bug or not, but it was a MAJOR useability problem with ArenaMaster).

The requirement for the mod is that you can only target people using the frame if you were able to mouse over them before entering combat. If not, then you have to target them manually.

That targeting error in ArenaMaster was because the guy was dynamically growing the frame size while you were in combat, the latest version of it sets the frame size to 5 all the time so that everyone lines up correctly.
