dynamic

I have a node type Gallery and I am building a view that displays each gallery as a grid of thumbnails. The view has one argument: Node ID. I need to add that as as an exposed filter so the users will see ALL galleries in a drop-down list and when they select a gallery, it will be displayed below.
The catch is that the list of my galleries is not static - I can add/remove/rename existing galleries. Basically I need the drop-down list to be populated from another view.
What is the best way to do this?

I need to display a panel in the context of a node and I need that panel to dynamically get its title from the node's context.

How can I do this?
