Hiya, i've just purchased the Sony Reader (waiting for it to be delivered right now) and have been testing your program.
It looks great!
I got some ideas for user friendly improvements though.

I have a lot of manga zip files organized into neat named (sub)folders and the zipfiles themselves are also named.

It'd be handy if a batch option is available, where you just save your settings, and then select a main folder (for instance Death Note) and it will just go into the directory, searching for available zipfiles.
Each zipfile will then be automaticly made into a pdf-document.

Another thingie is that in windows, each time you chose "Add files, directory or zip" it will jump back to "My Documents". If it remembers it's last directory then it would be much easier.

Also, in images, I think it'd be easy if the image dimensions are used to automaticly rotate a landscape image. I mean, you detect it already with H/V, why not make it rotate automaticly?
And a filter to not include certain named files is handy too (like coverpages)

Are you planning to release the code into gpl? if so, I might be able to help out a bit, although my java is a bit rusty...
