phpbb path problems ( invalid or have no access)

I just learned how to use Drupal and successfully integrated phpbb with drupal. the problems are:

1. path of phpbb. phpbb forum is under the dir of localhost/drupal/phpbb3, and drupal is under localhost/drupal. So in phpBBforum settings for phpforum path I filled " phpbb3/ " and I did receive "Successfully locating phpBB installation." but when I try to creat a menu I fill in the blank "phpbb3/" I got "invalid or dont have access to it" . what is the problem?

2. in /phpBBforum settings/, I did ask phpbb forum to 'display in frame inside Drupal page' but it seems not working as well.

btw I found http://drupal.org/node/275016#comment-896846 , it is not helping. I did exactly nothing wrong according to it.

3. Another question, I dont like the way Drupal pulishes stories and things. I want the pictures uploaded can be displayed directly in the stories, I want something more such as the html codes (things you use when you post a thread in a forum). Is there any module I can use to replace the current one? what is the name of current module that provides that funchtion of "publishing"?

Thank you very much!
