Any thoughts on how to best implement this? The only information I've

just .PNG files for markers; one example had a route that was drawn
from an XML file). I'd need to calculate the arrow based on direction
to the destination (direction the arrow points) and the relative
distance to that location (arrow length), so the overlay is something
I'd have to come up with at run time.

Sounds like you need a custom Overlay. Extend the Overlay class and implement the appropriate methods, like onDraw, for example. 

I think the main challenge is drawing the clickable arrows, but
another question that comes to mind is, should I search using the
Google Maps API, or is this job more suited to the Google Places API?

Google it, research them both, see which is better - that's not related to this list.
