Wufoo forms

I'm having a difficult time digesting the how-to on presenting Wufoo forms inside lightbox-type modules.

http://www.wufoo.com/2010/07/07/how-to-load-a-wufoo-form-inside-a-lightbox/

Could someone break this down to me (or tell me what/where to read/look), especially details involving how I'm to handle the resize callbacks when attempting to use Colorbox to achieve this?

Thanks,
