White label MarketPress, rebrand.

So I started setting up MarketPress on a site and I'm surprised as to how many links there are back to wpmudev.org and the branding of the "MarketPress" name used throughout. Also, that there are plugin installation instructions available to blog owners on my network.

While integrating this into a site I'm trying to make it as seamless as possible and to make it look like a natural part of the site but the fact that the plugin displays links back to wpmudev.org support forums and manuals while also using the "MarketPress" name it's not meshing well.

Are there any systems in place to easily rebrand the plugin, remove these links and other out of place elements?
Should a blog owner be allowed to see plugin installation instructions? and permalink suggested settings?
How do I get the video to play in the help section?

Thanks!
