The interface you just described seems like a bit of a disaster, and 
there are probably nicer ways to do it.  But...

It should be possible to see if you can retrieve one record from the DB 
in the relevant alphabetic range.  If so, then make a link.  If not, 
don't.  It's that simple.

You might want to look at Haml, which gives you prettier syntax and CSS 
abstraction.
