Re: Thinking of using bbPress for a forum…
I’ll take a crack at this!
1) I’m not sure about this, but if it doesn’t exist then I’m pretty sure it can be added through a plugin.
2) The “bb-attachments” plugin allows users to upload images and other files: https://bbpress.org/plugins/topic/bb-attachments/
3) I was able to match the look of my WordPress blog to my bbPress forums pretty easily
4) There’s a five star rating plugin here: https://bbpress.org/plugins/topic/bb-ratings/
I’m a big fan of bbPress, and have been using it for over a year. There are some people who have mixed feelings on bbPress though – you can read about that here:

I haven’t had problems integrating signin or matching my theme. However, I have a site with one WordPress install and three bbPress installs, all using a shared users table… and each system has its own profile link. I hear that BackPress should solve this eventually (a single profile system that will integrate across multiple installs like this), so I’m sticking with the *Press platform for now. But it’s been my biggest issue so far, so thought I’d share in case it’s something you need right away.
Good luck!
