Sure, you can always have macro that chops the first token as a first
argument, and all other tokens up to a marker (one that will *never*
appear in normal text) as a second argument.  Try this:

[-- Begin LaTeX code: ---]
\makeatletter

% Split the first letter from all following ones; terminate at
% "@StrEndMarker@" (without quotes).  Example:
% 		\CapitalfirstParse abcDEF at StrEndMarker@
% 	#1 is {a},
% 	#2 is {bcDEF}
\def\CapitalfirstParse#1#2 at StrEndMarker@{\uppercase{#1}\lowercase{#2}}

% Add a marker at the end of the string to capitalize, and pass the
% result to the parser:
\newcommand{\Capitalfirst}[1]{\CapitalfirstParse #1 at StrEndMarker@}

\makeatletter
[-- End LaTeX code. ---]

May TeXnology take care of us all,
