Other than publically available documentation on various web sites, including
IBPhoenix.com...

You could invest in a copy of the IBPhoenix developer CD it has
A Firebird Reference Guide, and using Firebird manuals, you can use these
along with the latest release notes. We also have on the CD a document
entitled Understanding the Firebird Optimiser, that you may find useful along
with a number of other advanced documents. Finally you could laways buy a copy
of Helens book.... thats the most upto date source of info.
