Ha, love a good zombie thread!
It's really true that iMore has the most helpful members out there (and I've been on a lot of iOS forums--in a lot of them it seems like many posts never even get answered at all). I don't really mess with theming much myself when it comes to the springboard--too many variables with all the different icons--so I limit myself to the lockscreen, the statusbar, and the layout of my springboard. Here's my current setup:
Tweaks are: Infinidock and Cascade for the dock, Springtomize2 for icon sizing/extra rows, Winterboard for Mail icon.
I will say that some of the options in Springtomize2 are nice if you want to apply some global theming to your icons: grayscale or sepia tone, for example. Much easier to implement than trying to keep up with everything individually. Anyway, I'm sure this thread will help someone, somewhere, at some time!
