Filter Map based on taxonomy / customize associated posts content

Using Google Maps in our theme. Client wants us to do two things which I'm not sure this plugin supports.

1. Wants to be able to filter the map results based on several custom taxonomies. So if the user wants to see posts associated with term X and category Y the map would only show those locations. I saw in one of the other threads a dev mentioned you can do queries based on taxonomies but I don't see any documentation for it. How would I be go about doing that?

2. The client wants to show the taxonomy terms associated with each post in the map footer. As well as some of the content. Is this possible with a filter or action hook?
