From my list? Honestly I read chronological and am working on the Force Heretic trilogy at the moment so no spoilers past that point, so I can only help you up to that point.
The Jango and Zam comics were very cute, but focus more on Jango than Boba.
Tales from the New Republic has a very good story about him, but it also has a bunch of other stories about other people too, so that's more of a book I would get from the library if you can, rather than buying. Unless you want to collect books, then go ahead and buy it.
Enemy of the Empire was good.
Shadows of the Empire is good, but it doesn't focus on Boba, he just happens to pass by in a chapter or two.
Tales from Jabba's Palace is a good buy, but again it only has a short-story. There are stories of other people in there too.
The Bounty Hunter Wars books are good.
Reality doesn't care if you believe in it.
