Site/Forum Design

[looksee]

Hi all,

I'm considering buying the vBulletin full Publishing and Mobile Suite. However, I am trying to achieve a certain site design. Specifically, I want:

1. The Home page to be essentially a blog page.
2. As part of a blog post, I want to be able to post a pre-recorded podcast. Can I add an MP3 somehow to the blog application?
3. The actual forums will require registration to view and to post.
4. I want to also host webinars on the site and offer it only to those who are registered on the forums.

Is any of this possible with the Publishing and Mobile Suite?

Thanks!!
