Accepted Norms
The currently accepted prime meridian of Mars is centered on the crater Airy-0. From there you can measure longitude using any system, degrees/minutes/seconds, decimal degrees, east/west, positive/negative, [lon, lat], [lat, lon], whatever. The prime meridian's location is fixed, but after that all bets are off.
MOLA data uses planetocentric latitude (as opposed to planetographic latitude).[1]
There is a system of quadrangles invented by the USGS which are occasionally used.
The zero-altitude datum is not officially standardized, though most maps I've seen use MOLA elevation data, which is defined to be relative to a datum defined by the gravitational field of Mars.[1]
