some cruising guides. The Cruising Guides to the Canadian Maritimes (Cheryl Barr) will cover some our your route. If you can find a copy of Cruising the Eastern Shore by Mike Cox it would help. The Binnacle.com or The Nautical Mind will have Cheryl's book. The CCA Club has a Guide to the Nova Scotian Coast but I've never opened one so have no input there. If you go on the Province of Nova Scotia's Tourism website you'll find a free guide to sights to see and events. New Brunswick and Prince Edward Island would have similar. It might help you decide what you want to see.
