The following simple solution gives you the name of the documentclass in 
\firstClass:

  \def\firstFile#1.cls#2\@nil{#1}
  \edef\firstClass{\expandafter\firstFile\@filelist\@nil}

It works in the standard situation where \documentclass is the first 
command in the document. It just extracts anything before ".cls" in the 
filelist. If you want to cover the case where someone uses \input before 
\documentclass, you can add the following line after the two lines 
above. It just throws away all other file names before the class.

  \@for\@Filename:=\firstClass\do{\global\let\Classname\@Filename}}

The name of the class is now in \Classname.
