Map production is in GRASS a little bit tricky, even for those, who did never use ArcGIS before. You have to create configuration file, and run ps.map with it. Advantage is, you can automate the whole process. Configuration file can be generated on-the-fly and reused x-times. Disadvantage is, you have to crate the file. See ps.map manual page for more info [1]. As for scripting language: You can use actually every scripting language you know. Preferably BASH, but you can use Python and Perl as well, and I would not be wondering, if VBA would be working as well. See g.parser manual page for details [2]. Anyway, you should get familiar with the command line in GRASS, because of scripting in GRASS does use the same approach. You are not working with objects, you are using whole modules, which are doing the work for you.
