Looking for a Facebook Customization Resource

Anyone know of any sites that have info on customizing facebook? What im looking for is an information source that contains info about the many aspects of customizing a facebook business page.

Thanks.

I normally wouldn't post something like this on any forum but it seems my Google-Fu isn't what it used to be.

I am with you, you can find a few crappy templates but most of this is kept on the hush because people would rather charge you 100+ bucks for something that is probably simple by offering a customization service. In other words.....good luck.
