The back plugs near the intake manifold can be a pain to replace, but doable. You will have to remove the intake and a whole bunch of bolts in and around it to access the plugs.

Now coming to torque, this is my take on torquing plugs. I usually have a hose that I plug to the top of the plug and after applying anti-seize slowly thread it in. With the hose on the top of the plug it is nice and easy and once I have tightened it till no more with the hose, I take off the hose and put in the socket and tighten 2/3rd of a turn and thats it. Put the coil over it and you are done.

In essense you need to be nice not to cross thread the plugs (remember it is all Aluminium out there that is soft), anti-seize and 2/3turn.

Hope this helps.
