the a/c is pretty straight forward, you can just remove everything that has to do with it and cap the lines that go into the cab. when you remove the bracket though you can either cut the bolts shorter or get different ones to put back in the motor so the timing chain cover doesnt leak. i just cut mine. i pulled all mine out about a month ago. the little raiator deal, and a few other lines..it was easy. as far as the smog pump goes i dont know, i have the same year truck with the same motor and mine didnt have a smog pump...
heres a pic of what mine looks like with it all gone.
