<<Has anyone installed a hydraulic pressure gauge on the 320 gear system? 
If so, how do you monitor the two sides?  Got a valve to recommend?>>

Naf,

There are a number of 320/360s with permanent pressure gauges installed.  They are immensely valuable for troubleshooting anomalies(both in the air and on the ground), performing maintenance tasks and general peace or mind.  I added mine a few years ago by simply adding T-fittings to the existing lines.  Separate gauges monitor high and low circuits.
