How to backup ONLY preferences with SPB?

[slickware]

So, I keep re-cooking the NoChem rom to make it how I like it, and I'm really getting tired of inputting all my phone's preferences/settings (text size, data-connection-settings, etc).
Where are these settings located? Can anyone tell me how to back up JUST the settings (and not any installed programs or anything) using SPB Backup?
That'd be a HUGE help!
Thanks!
