Some resourses that I would recommend are Skipper Bob books, "Marinas Along the ICW" and "Anchorages Along the ICW". The latter gives bridge information which you will require. You can order them on line at Home | Skipper Bob Cruising Guides
On his site he also has waterway updates. Another resourse is The Active Captain here https://activecaptain.com/X.php
which is an interactive cruising guide book and excellent if you have internet aboard.
With your specs you can do the Dismal Swamp. They close the canal from time to time because of low water so check before heading that route. If you plan to go as far south as Miami note that the Jean Tuttle bridge just north of Miami was designed by a dyslexic engineer and has only 56 foot clearance instead of the usual 65 feet.
