heh… how cool - you do obey to my orders 
seriously, glad my guide appearantly was a helpful kickstart.
I gotta tell you though, each time I render something new, I find myself tweaking for hours and discover yet another comibination of settings
you can really get quite a lot out of the Zbrush rendering if you take your time.
the last few days I had to render pretty large images, since they are intended for print on a 130 x 110 canvas. while it does take a considerable amount of time, it still seemed faster than Mental ray for example. At least you don’t have to do all the migration and translation process of map creation, mesh exports, displacement and whatnot to get it to another application.
