You can use the nsExec plugin, or some other exec plugins, to execute regasm. I'm not familiar with regasm specifically, but I'd expect you don't really need to set the working directory. Just add the path before the filename.

As for setting an environment variable, that's been asked before. You can find the solution using the Search function.
