For the Abacos, I've been very happy with Dodge's guide. He talks quite a bit about crossing, etc as well. An overall Bahamas
guide I've used is Matthew Wilson's "Bahamas Cruising Guide", though in the edition I had, he did not cover the Juamentos and Ragged Islands. I liked that he had yellow pages that give one some idea of what services cost.
I've never been south from the Bahamas, but have read and love "The Gentelman's Guide to Passages South." What I learned about how to use weather
to my advantage from that book has been invaluable.
Although I've never used them, I know some cruisers have used the guides by Pavlidis (sp?). I believe he covers the Juamentos and Ragged Islands.
There are also some wonderful cruisinig narratives or cruising logs
you will find by surfing around which will give you many insights into what cruising is like there and what places might appeal to you.
I have some Abacos photos at:
