sam2kb has a b2 to wp converter but he hasnt posted a plugin thread for it i guess.

It migrates b2 to wordpress almost perfectly.You might wanna pm him for the details.

btw; most post data resides in evo_items and it's subtables, along with a few other tables.

You are looking for the BIMP Importer

You can easily migrate b2evo blog(s) to a new or existing wordpress website. It's a paid script though.
If you are looking for a free way to migrate the posts, try the RSS importer shipped with wordpress.

You should make a migration video for the plugin for the people to see how it's worth every penny of that 19$ (:

Yeah, that's a good idea.
