expose correctly, keeping histogram to right side...but not clipping highlights...better to use higher ISO than to fudge exposure with lower ISO...

Is it easier to salvage the picture if its overexposed or underexposed? Is it safer to underexpose by 1 stop all the time so as not to get blown highlights?

it is easier to salvage underexposed...but the salvaged part tends to be very noisy...if its a once in a lifetimediediemusthaveheckthenoiseandexposure-type shot, can underexpose slightly...if going for less noise, try exposing so that the histogram is to the left but no clipping...due to signal-to-noise ratios and other mumbojumbo, the right (bright) side will be less noisy than the left (dark) side...
