I think that should happen automatically, but I never use that feature so 
someone else will have to help there.

I think the easiest way is to do the following

M-x customize-variable RET LaTeX-math-list RET

Then click INS, and for "key:" click on the value menu and select "Choice".  
This will bring up another value menu       which should already be selecting 
"Character".  Then delete this character (namely ^@ or the null character) and 
type "f" since that's what you want to press.  The next value menu should be on 
"Macro", so just type "iff" (notice the lack of "\").  The last two are 
optional having to do with where it appears in the menu, but I would make the 
first "if and only if" and leave the second as none.  Then just click on "Save 
for future session" and restart emacs (I couldn't figure out how to get it to 
work without restarting).


In case you don't like Customize, this should translate to the lisp expression

'(?f "iff" "if and only if" nil)

So something like (untested)

(add-to-list 'LaTeX-math-list '(?f "iff" "if and only if" nil))

in your .emacs should be sufficient, but you will have to ensure that latex.el 
is loaded first.
