with lots of help from the people around here, I finally have wp up and running, I just moved it to the main dir, all others files of the site are rewritten to use the wp-templates and I've deleted the old b2-installation.
But now I have the following question:
what files can safely be deleted from the main wp-dir?
I mean, I quess the readme.html or the import-files from the admin-dir can be deleted, but what other files can be deleted as well?
Thanks for all the help so far!
