Take a look at the build_new_post() function in ./includes/functions_newpost.php, and the class structures in ./includes/db_class_threadpost.php.

The former shows you how vB itself uses the datamanagers ('Post' and 'Thread_FirstPost' in this case) to add new threads and replies. Obviously there's a lot of extraneous stuff there, and it is getting the data from posted data rather than an external table, but it's easy enough to pick out the bones of what you'd need in your script. Note the way it picks a different datamanager depending whether this is a new thread or a reply. Also note what it does if userid is 0 (i.e. not logged in).

The latter (the db_class_ file) will show you what is required and what is optional as far as the dataman fields are concerned (find the $validfields declaration for each class in that file).

Unless you have a zillion forums, I'd suggest creating the new ones by hand and just building a simple array by hand to do your forumid translation. That way you don't have to learn the forum datamanager as well.
