Ok that should be fairly straightforward. If you have an $_items array for the shows the profile is attending you can pass that into the maps function something like this:
{if isset($_items)}
{ujGoogleMaps_map name="multimap" map=$_items module="jrEvent" height="300"}
{/if}
You can try using your module rather than jrEvent if that is where the map data is stored.
