Regarding software-list ROMs... add them to one or more of your "rompath"'s, just as you'd usually do this with MESS alone. That is, all games for a2600 for example should go to <rompath>/a2600/...

Regarding ini's... I assume you're talking about each machine's MESS ini file here!? If so, please read this FAQ carefully! That should clarify most of your questions.
