where to start and what comes standard?

I want to start a webshop and i want to know what software is the best to use and which one has the most features?

There’s an overview of porting a site to MODX here: http://bobsguides.com/porting-your-site-to-modx.html, though it neglects the automated importing of static pages.

There is some coverage of that in my book (hopefully out soon).
