Is this method more efficient than the other method you gave?  I  
currently have custom sorts that look up the data, rather than  
pulling the data into the pages as page variables from the get go.

Other method -- I have:
// custom page sorts

     function DataCompare($x, $y, $var) {
       ## get the Data- versions of the pagenames
       $datax = 'Data-' . PageVar($x, '$BaseName');
       $datay = 'Data-' . PageVar($y, '$BaseName');

       ## perform the requested comparison
       $c = strcmp(PageVar($datax, $var), PageVar($datay, $var));
       return $c;

     $PageListSortCmp['year'] = 'DataCompare($x, $y, "$:Year")';
     $PageListSortCmp['work'] = 'DataCompare($x, $y, "$:Work")';
     $PageListSortCmp['wauthor'] = 'DataCompare($x, $y, "$:WAuthor")';

And it's working!  Much to my relief.

I have categories such as Category/Author-AuthorTName -- when linking  
to them from pagelists I have to pull the "Author T. Name" from the  
page data to build the category link.  That T. in there is a real  
problem, so the period needs to be stripped.  While I'm at it, I  
strip all illegal characters from the pagename -- might as well.  If  
I don't need to do that,  I can change to str_replace, though.

     $FmtPV['$sWAuthor'] = "preg_replace('/[^A-Za-z0-9 -]/', '',  
PageTextVar('Data-'.MakeBaseName(\$pn), 'WAuthor'))";

I might need the : in there if only because a book title with a : in  
it would keep the colon in the Category/Title-Book:AReallyLongBook.   
Otherwise, I don't really use :'s in Category titles.

So far my custom link markup seems to work just fine -- it strips the  
illegal characters, and doesn't seem too slow.

Great, this time I'll comment WHY it's there so I don't forget.  You  
never think you'll forget something til you forget it. :P  Given my  
circumstances, I really ought to know better.

One more question:

How would one use a searchbox to search a specific field.  I have the  
alphabetical links that do $:Work=T* -- if I want the contents of the  
searchbox ("Blue") to become $:Work=*Blue* so that one can find all  
pages with Blue in the title.... is there a way to transfer q=Blue to  
$:Work=*Blue* ??
