Adjusting a chain is so simple yet so troublesome. If the chain is too tight, it will accelerate wear on both chain and sprockets. As it wears, it may cause the chain to break but I think that would be pretty extreme.
The addition tightness causes drag and that increase engine load and reduces mileage.

As for doing it right, I adjust it so that the bottom of the chain(closest to the ground) will move up and down about 3/4inch. The best way to do this is to have some one sit on the bike after making an adjustment to see if you have that 3/4 adjustment.

The big thing is to pay attention to the alignment of the chain. You want to make sure the wheel stays straight and that you adjust both sides equally.
What I do is to measure from the swingarm to the rim on both sides and equal them out, then turn the adjustment nuts an equal amount on each side to keep it straight. It works for me but you will want to experiment to see what works best for you.
