You should become familiar with the Scheme language. To do that, get a copy of 
the R5RS (http://www.schemers.org/Documents/Standards/R5RS/r5rs.pdf) and read 
it. Just be aware that not everything mentioned in the R5RS is implemented in 
the Scheme interpreter of Script-Fu. Items like define-syntax, or bignums are 
examples of items not currently supported. Also, look at the scripts which are 
shipped with GIMP.

I think one of the problems people have when learning Scheme is that a lot of 
scripts are shown with many closing ) symbols at the end of a line. While you 
are getting comfortable with Scheme I would suggest you don't skimp on the 
whitespace. Put the closing parentheses on separate lines. If may violate some 
Scheme based coding style guides but makes it much easier to see the syntax of 
the language.

There are tutorials on the GIMP web site at http://www.gimp.org/tutorials/ 
under "Script Authoring". I also have some notes about Script-Fu in the wiki 
section of my web site at http://www.ve3syb.ca/wiki/doku.php?id=software:sf:start

Be careful of any Script-Fu tutorial which was written before the release of 
the 2.4 version of GIMP. It may contain information that is out-of-date or 
even wrong as GIMP has moved to a different Scheme interpreter.
