What is the syntax for calling a vbscript function from an event (OnFirstUIBefore) in the Setup.rul file? I have the script included in a custom action and stored in the binary table (I'm assuming that's necessary to allow the function and script to be accessed when the client is running the install).

I'd try the Windows Installer API function MsiDoAction with arguments ISMSI_HANDLE and the name of your custom action (as a string). It's at least documented to do what I think you want, within some limitations mentioned in the Windows Installer SDK help.
