First thing, get out of PUA right now. Listen to these podcasts to find out why:

Next up, what the Hell is the 'Attraction Phase'? This isn't a game of chess, its about fucking women. And as for the advice - what you're saying means 'jack shit'. Not jack shit: BULLSHIT more like. Faffing around with that is all about avoiding rejection, something which is inevitable every now and again.
You want to know what to open with for a girl, here's a suggestion:
"Hi. You know you are a very attractive girl and I think we should hook up in the near future"
Don't lie. If you're a virgin, there is nothing wrong with telling her you find her desirable but you're nervous because of your lack of experience. The best thing you can ever do for yourself is learn to tell the truth unconditionally. Notice what you are feeling and report what you are feeling to the people around you.
Here are some people you should look into - learn to be a MAN, not a PUA. These MEN will help you:
Alan Roger Currie, Steve 'The Dean' Williams, David X and Brad Blanton should all be of immense use to you. Oddly none of them have stage names (apart from David X, and 'The Dean' I think is a nickname)... and don't confuse Direct Game with DIRECT. Direct Game is a logical fallacy, so no Sasha or any of those silly twerps.
