I am left handed, right eye dominant and play right handed. If your question is that you want to have better alignments for your irons? It really does no matter too much which eye is dominant. To get proper alignment all you have to do is:

Stand behind the ball and pick a spot about a foot in a half in front of your ball and you indented line. Then address the ball with your club face first to that spot. Now step into the address with your feet along an imaginary parallel line and everything will take care of its self. That spot is within your periferal vision so you can keep that imaginary line there during your takeaway and followthough.

At the range, always put a tee out in that 1.5 foot mark..easier to see and move around. I don't like the club shaft pointing on your toes, because that line it not rally the true line, it is a parallel line that should alway be left of the target (RH).
