u should optimize at least ;)
everything which is optimized for x86
and gprof can give some coarse hints too
and when in doubt if a specific piece of code is worth the troubble, just 
comment it out and benchmark to see how much time it really uses

for (i)dct specific docs ... well i dunno many, mostly the different versions 
from mplayer/ffmpeg, especially the older ones as they are more readable
but beware, the idct is pretty sensitive to rounding errors, a few rounding 
errors at the wrong place and ppl will turn green after a few seconds, or get 
stripes ;)
