My method was to take a short ride in the shoes with the exact clips and pedals I would use. Be sure not to jam the toe against the end of the toe clip, but leave it back a whisker. After a few miles, remove the shoes. You should have a line on the bottom of the shoe from the back cage of the pedal. I then mounted the cleats with the slot set towards the heel another 1/8 of an inch, to make sure I didn't get numb toes from the shoe being jammed against the front of the shoe. Be sure to hold you feet steady at your optimal pedaling angle. If you move your feet around you end up with 3-4 lines on the sole.
As far as nailing the cleats on, your on your own. Harvey Sachs in the DC area is one person who can get this done: he even has his own cobblers anvil.

I have a pair of Vittoria shoes to which I need to attach nail on cleats (Tacx brand). Does anyone have a method to determine optimum placement of the cleats on the shoe? I am riding with Campy NR and SR pedals with Ale, Christophe, and Campy clips. I was going to convert to the modern shoe/pedal combination but gave up trying to find a size 51 narrow shoe :o)
