Developing a website around PunBB 1.2.22

Hello,

I'm in the process of developing a custom website around PunBB. My intention is to use punbb's user login system to manage users of the site. I was wondering if anyone could point me to a couple of mods maybe?

I'm looking for:
  - A private messaging system
  - A Shoutbox
  - A Lightbox photo gallery that will allow users of a certain group to upload images.

I chose PunBB 1.2.22 because I have used it in the past, and I enjoy the fact that its simple to use.

Thanks,
DirtyDeeds
