This thread has some good pointers, but it's always best to speak to the engineer who wil be cutting the record. If he's got good experience and some decent gear then he will know exactly what to do anyway, and you need not worry about mix details - he'll do it for you. Oh except the 2 points about not panning bass and not having crazy top end!
I send a version without peak limiting at a lower average level because that can sound lots punchier.
The level limitations of vinyl are the length of the cut and the ability to track the record. A hot digital level buys you nothing but extra distortion and less impact.
