Remove Gallery, HTML, Release badges?

The link in the wiki to "Remove Gallery, HTML, Release badges?" doesn't work. It's actually linking somewhere else. I kinda need this part. So far I've been able to remove the login link and sidebar by editing GalleryCapabilities.class. I'm only going to have 2 or 3 specific galleries that will never change. I want standard users to be able to just see the galleries and search them. I want to strip down main.php so I can include my particular galleries in other PHP like this:

<?php include("http://www.example.com/gallerytest/main.php?g2_itemId=37"); ?>

so far this seems to be working but I want to strip it bare and just leave the pics and no other info. So I'll need to remove the Gallery Logo, some of the HTML and I don't know what "release badges" means Could somebody explain that?

Anyway I'm not asking anyone to write the code for me I'm just wondering if anybody could point me in the right direction please?
Thanks

Also I'm looking for help with one other thing:
I also want to add nominated users that can upload to their own specific galleries and edit their own galleries but they can't edit other users' galleries.
Does anyone have any experience with this / does anyone know if it is possible.

Thanks again for reading through my post.
