Do you have the change icon label color enabled or something like that on speingtomize and also something like white icon label checked on winterboard? Take a screenshot of what's checked on winterboard and post it here.
Uncheck everything on winterboard except the theme and try speingtomize again. You have way too much stuff there. Keep it as minimal as possible. You need to learn how to use ifile and apply everything on the theme, but that's another thread.
first time I jailbroke my iPhone 4 I had to restore it twice, you can't ever learn enough when it comes down to jailbreaking. Don't worry, we are all Newbies. Download ifile, it's free, and little by little you'll learn too. It's the most essential tool and the first thing I download as soon as i JB.
iFile is a powerful Cydia program that allows you to access and edit the files on the phone. The alternative is computer programs (WinSCP, Cyberduck, DiskAid) that connect to the phone via USB or WiFi. If you're going to continue to theme you'll need one of these sooner or later. One of the advantages is that you can combine and put together your own themes so you don't have to apply so many in WinterBoard. For example, I have one that has a custom dock, icons, battery replacements and lock screen slider boxes as well as transparent images to hide the rotation lock.
Springtomize can be buggy, especially when it and WinterBoard are used excessively, so try cutting back on them to decrease instability.
