Ryan, I like what you've put together there. If you can make a quick guide link that pops out at new users looking to install Ubercart for the first time, it should help to limit the amount of people who get confused and discouraged.

One thing I noticed on the pdf was that all of the Ubercart links were taking me to page cannot be found, and the FAQ link was taking me to an access denied page.

I like TR's idea of forming installation profiles of sorts too. People often ask questions like, I want to setup a store that allows file downloads, sells t-shirts, or allows custom text on a product. Installation profiles might be nicely supplemented by recipes as well...now who feels like writing up some documentation?
