Say also how would you like to be approached or better still how you would not like to be approach and also what you do not want on your first that.

The only way to go wrong with approaching is by doing it either when I'm already in conversation with someone (it makes it awkward, especially if you're not a mutual friend) or by saying something awkward like "hey, future wife" or "Hi, girlfriend!" ... it's way too soon for certain comments. So keep things casual, do it when I'm alone preferably and don't say something that will make the rest of the convo awkward.
As for a first date... I really don't care but a dinner date is always good and really gives you time to get to know the person. Plus... food. Any activity that is accompanied by good food is fab.2
