csv Question

I am trying to add ‘Comments’ and also Google Maps to some listings via my csv file.
My questions are:

1) Re comments, my keys are ‘comment_count’ and ‘comment_status’ – what do I need to enter into these in order to activate comments.

2) How do I activate Google Maps, I’ve checked out previous threads on the forum, but I’m still none the wiser … looks like it might be a complicated process?!? My keys are ‘map-loglat’ and ‘map_location’
