Hi Ty -

It looks like you are just getting started with Qi. You may find that my 
boostcon'10 presentation on Spirit will get you up-to-speed quickly.

You can find the slides here:
<http://www.objectmodelingdesigns.com/boostcon10/>

and the video of the talk here:

There is an active Spirit ML that responds quickly to questions. The 
Spirit web site also has a lot of information:
