Have you tried tapping on the position display (the box in the upper right hand corner with the coordinates, elevation etc listed)? Tapping it should bring up options for sending (by text, email etc) the coordinates in the position display. Keep in mind that the coordinates in the position display are always for the center of the mobile map viewer (where the cross hairs are).
And markers are associated with the map itself. As long as you save the map initially, any markers you add to the map will automatically sync. If you're new to CalTopo, this page on our user guide helps explain how the app works, including the relationship between map objects (like makers) and maps: https://training.caltopo.com/all_users/getting-started/first-map
