Hey Greg, I too am a recent convert to TrackIR (in preparation for the 777). I found that using EZdok to focus on certain areas of the flight deck to be the best option. It will take some setting up at first, but once you get it, you'll eventually get used to it. Now when I fly, even though I love the 2D flight deck, I haven't gone back to it ever since I made the switch. For my FMC setup, I use the 2D popup, rather than the EZdok focus.
Take a few moments with the EZdok setup, get comfortable with it and TrackIR, and you'll see how quickly it becomes natural to you.
For those times when I just want to flip a switch from a distance (like the packs or the lights) I just rely my memorization of the overhead panel from continuous use. But other times, like for the IRS switches, I use EZdok.
