First, It is not called the idler arm. It is called a pitmen arm it it requires a special puller to remove it from the gear box.
How much torque do I use to tighten the idler arm
I don't believe there is an idler pulley on that model, just a tensioner pulley
NO it is not.
The idler pulley has nothing to do with the brakes. If the idler pulley is bad it could throw or break a belt, and then your engine will stop.
The Chevrolet S 10 pickup truck idler arm can be removed by removing the idler arm retaining bolts. The idler arm has two retaining bolts. Reverse the process to install the new idler arm.
Yes.
Remove the nut holding the idler arm to the center link. Separate the joint with a "pickle fork". Remove the two bolts and nuts from the frame end of the idler arm. Remove idler arm.

NO
According to my internet research, to change the pitman and idler arm on a Chevy truck, one must remove the two bolts holding the idler arm as well as the nut holding it to the truck. Then to remove the pitman arm, remove the nut and the drag link.
