Pioneer 111FD calibration questions and concerns

I'm new to all this and know nothing about calibration. If I choose to have my elite calibrated what should I be looking for? better color reproduction? darker blacks? Or is this TV pretty much so good, unless your a total videophile (i'm not) it will be like throwing money down the drain? Or is it a crime to have this TV and not give it the best treatment? Also what is all the ISFccc about? controlcal? etc? My TV is also very close to the wall, if they cannot access the service menu is it even worth it to have someone come out? Or is accessing the service menu absolutely necessary?

Any other info is helpful, thanks.

thanks that's helpful.

i'll post here as I also PM'ed you as well in case you don't come back turbe.

But thank you very much. I will read through all of that a bit later today. My only question is you have to access the service menu to get the ISF modes correct? Because that's what I want. I'm not going to pay $300 for someone to fiddle with my remote. I can do that and have used d-nice's settings but I want the absolute most this set is capable of. Thanks!
