Yeah, probably not worth it. Mostly I was thinking in terms of if you ever move and want to leave the place in good shape.
the current bolts that came wit the mount are grade 2 (thanks for the link I would have never known) I think I will purchase new grade 8 just to be on the safe side.
One more thing, tv along with the mount are really heavy, the manual said something about using straps with heavy duty wire as a precaution in case the mount breaks free from the wall, is this overkill, I am just a little concerned that I should use some kind of safety in case of this?
Properly installed with good quality bolts, mount, etc. it should be virtually impossible for a heavy TV/mount to come out of the wall. Most of the force is straight down so you'd have to shear through all of the bolts. Even cheap bolts should be able to handle that but
the bolts you have sound like Really Cheap
bolts. I think you'd do well to spend the few dollars for better bolts/washers.
Also, setting you clutch fairly loose so the drill can't over-torque the bolts really is important. As someone else said, finish them off with a manual socket set and then you
will feel how much force you're using. After all, the only real goal is to get the bolts snug
-- i.e. the mount doesn't jiggle around the bolts. There's no extra strength imparted by tightening them further since this is a static load.
