Start on the center nut and x pattern your way to the outside lube studs with antisieze and torque slowly if it feels like it will not torque to 17 ft. Lbs. Go for lower number 16,15 ft. Lbs. Even torque is better than overtorque. Best of luck to you.

Depends on the gasket.. that may be true with the old graphite gaskets, and I think that is way high for those as well, but definitely not with the new style silicon bead....they are more like 6lbs. Hand tight with a twist....Start in the middle, work your way out up down in x pattern, just like a cylinder head....

To answer your questions:
1) Yes - Loosen 1/2 turn retighten. Assuming they were not over torqued, if they were, and you have silicon gaskets, you may want to replace.
2) Yes
3) You don't need a torque wrench for this, "one hand only" on small 5-7inch 3/8 ratchet, snug with a 1/4 turn.

You will be surprised at how little tight these need to be. If they then leak, just tweak them a bit more. You DONOT want to overtighten or they WILL leak, and you may possibly warp the VC's.
