Hi David,
about resistivity, you can find some documentation here:
In the documents of 2005 (6° Meeting degli Utenti Italiani di GRASS) you can see some slides (and some text, in italian...) about some very old projects in which we used 
GRASS to visualize resistivity data (we did a kind of DEM with normal "x" and "y", but we used resistivity value as "z"). Actually you could do the same with other 
software (e.g. Saga), but we used GRASS to further filter the data with R (statistical software). In the presentation "L'utilizzo di Grass in archeologia" you can check 
the slides 4,5,6 (GRASS) and 7 (R). In the article you can see page 9 and 10 (chapter 4.4 Prospezioni geoelettriche: raccolta,elaborazione, analisi dei dati).
Hope it is useful (even if the projects are really old...).
Nice greetings,

Luca Bezzi
