Aftermarket Gauges

I have a n/a 01 GT and was looking to put on some aftermarket gauges. I know everyone says get the oil, water, and volt gauges, but are there any other gauges that are worth buying. I was considering a/f ratio and vac. gauges. My car will stay n/a for now (no nitrous either), but eventually become supercharged. Any thoughts on what to get? Thanks
 
I just put in oil, water and vac/boost.

are you supercharged? Or can you hook the boost/vac gauge up to the vac. hose?

It's just a vac gauge right now, t'eed into a vac line. I didn't want to have to buy a gauge twice. I already spend enough money on this thing.... :)
