The default Android home screen is not themeable, so you will either need to write your own replacement home screen, or write a theme for one of the existing home screen replacements that others have written and support their own custom themes. Not all are free, and not all support themes.

I don't know much about writing your own Android home screen, other than a home screen activity should respond to the android.intent.category.HOME category in its intent filter (About intent filters).

You have to look at framework-res.apk - most modding is done there. Normaly you find it at /system/framework/framework-res.apk. You can open it with Winrar or 7-Zip and take a look at all the ressources in there.

For more just google it :)
