The easiest way to tell what you have loaded on the GPS is to simply zoom way out where you see a bigger view. The maps you loaded should be superimposed on the basemap which will show state boundaries. In the future, I believe you can save a .gdb file in Mapsource while you still have the desired map tiles selected after transferring them to the GPS.
Your ability to search the map is governed by how it was compiled and what POI's were included by the author. The info you are looking for may not be part of this map. You should be able to search for POI's using Garmin's own 100k Topo maps, or at least I am able to.
You may be able to download POI's for your desired area and install them with POI loader as well (or create waypoints from them). A little searching with Google should help you find them.
