Steve,

My best suggestion would be to get (if you don't already have it) the book "Atlantic Coast Lighthouses A Traveler's Guide" by Kenneth Kochel, Revised and Updated by Jeremy D'Entremont.

All the lighthouses are in there so between studying that and surfing the web for additional information you should be able to pick out which lighthouses you'd like to see that would fit into your schedule.

I've only been to some of the New York and New England lights as far as Portland along your route. If you have any specific questions on any of those feel free to ask.
