How to make a cheatsheet/crib sheet using Pages

I am starting a Developers Meet-up group at my sons' middle school, and I am trying to get ready for the first one. I need to make a cheatsheet/crib sheet for the participants ala http://www.cheatography.com/ in Pages, but I am struggling with getting the boxes to work.

What I need to make is something like a bordered Text Box, with the first line being a title section that has a background color, followed by some text in the body of the Text Box that is simply white background. Basically it should look like a little "window", with a colored title at the top and contents under it.

I can get the Text Box inserted, and I have a 1px border setup no problem, but I can't figure out how to get the title section to work. In fact, I can't even find where to set the background color of the text. I don't use Pages very often so I am struggling a lot to figure out where things are.

Once I get the Text Box working, I then need to be able to quickly replicate the Text Boxes for the various sections of the cheatsheet. I am hoping I can simply copy/paste more of them into the document and resize them as needed.

For the curious: The reason I am trying to do this in Pages is because my sons' school is an Apple Distinguished School. All the computers at the school are Macs, and all the students have iPads. Doing it in Pages allows them to park the digital copy somewhere the students can get to it to view/edit/print as necessary. I don't want to use http://www.cheatography.com/ because some of the details I need to include in the cheatsheet would not be appropriate to share outside of the school. My fallback will be to simply do this using HTML, but I'd rather this be in Pages.
