I can plot both using WXP from METAR data (I assume > they are the same basic data files, acquired via IDD through NOAAPORT) > so I assume that station pressure is in there somewhere.

If you are using the METAR data from the ADDE server, the variables are: PSL - altimiter setting (converted to millibars) PRE - sea level pressure If you are using a different data source, point me to a sample and I can figure it out from that.
