I use a json file which contains all the details about the layers I want 
to add to a map and how they will behave. I have then coded an object 
that reads the json and creates the maps from that. It gives me a 
generic mapping application that I can use in many contexts. 
(data.gns.cri.nz/dataportal - free registration required but there are 4 
maps inside that application using this method).

I would worry about a lot of KML files. They are slow to transmit and 
load. geoserver + postgis and sql views would allow you to do a WMS for 
display, WFS for query which would be a lot more efficient as your data 
size increases.
