Gauge Wiring Help
I'm not putting you down but this is one of the most basic of wiring items. Sometimes it's just better to admit you've never done something and get someone else to do it. If done incorrectly, this could cause a fire that would potentially destroy your car (not likely, but possible).
Can I simply wire them all in series, or is there some way to wire them in parallel that would be better? What size should the inline fuse be? Just looking for a few simple answers because I dont want to mess up $400+ in gauges.

Use the IGN port rather than the ACCY one in the fuse panel. It's a 15 amp circuit that goes on and off with the ignition switch. The ACCY port has retained accessory power (like the radio) and I doubt you need gauges after shutting off the ignition.
It will be easier to wire the gauges in series (less wires) and there's no real advantage to wiring in parallel but it means you will have to be more careful about your selection of inline fuse. The best bet would be to use 16-gauge or even 14-gauge wire but still protect the circuit with as small a fuse as will work. That would probably be a 5-amp or maybe a 7.5-amp. I'm not sure how much current draw you would have from your gauges but that should be sufficient to protect them from damage.
