You want a list of everything I've done with a font so far? :-p

In respect to hinting in DejaVu the only things you can really do is 
editing existing instructions and creating new ones for the new glyphs. 
Over the time CVT values were added, the fpgm table was altered etc.

After editing it's just a matter of testing it out -- you can do that 
within FontForge itself (grid fit), and then check in gwaterfall if 
there's not a weird problem at some size.

Only the first person who wants to work on the hinting needs to do some 
work to know what the important CVT values are, and that's basically 
reading the existing instructions and write down which values are used 
where. It's usually pretty straightforward (if it moves a point on the 
right side of the stem of "I" horizontally when the reference point 0 
is a point on the left side of that stem, then you know it's the 
horizontal stem width). But that requires understanding of the 
instructions of course (I don't know how much you know about it, 
should give you the real basics if you're completely new).

For hinting that's it really. I don't know what more you're expecting?
