Big Mike's EZ Niche Builder

I picked up Big Mike's EZ Niche Builder earlier this week, based on reviews I read here on the Warrior Forum. As someone who knows SOME (I use this term loosely here) about HTML, etc - I thought I would be ok. The user guide is very easy to follow (thanks Big Mike!), so overall I feel pretty good about doing the actual install, hopefully tonight.

A few things that confused me:

1. The user guide states:
You're going to need a one-page template that includes the layout and all of the common features of your web pages.
*Now, I've already picked out my template. But I am slightly confused by what is meant by "layout and all of the common features of your web pages." Is there anyone out there who can dummy this down for me?

2. The user guide states:
"Your template can be designed in any HTML editor and you can use the external CSS file provided or do everything inline."
*I understand about the HTML editor. Not so sure what this CSS jargon is all about. I did notice that in my download of the product, there is a file that has CSS in its extension....

3. The Tokens - I understand that they are placeholders. However, I am having a difficult time trying to figure out where I put them in the html code of the template itself.

I almost feel like I am making a lot of this more complicated than it needs to be. Of course, then again, I could be completely off base.............
