i am getting this motor from someone he has put in a cc 306 cam and has had some head work done. the one thing i know is the comprestion ratio is up just a tad (dont remember how much.

So what questions should i ask so i knwo what to tell the programmer?

the most important thing is going to be the flow rate. if your heads were flow tested on a bench (most professional porters will do this) then you will get a sheet telling you how well your heads flow at varying points of lift.
