It all starts with getting the PWF blueprint. But aside from that, you need to do some serious work on reprogramming your mind. There are several different things you mentioned, which are separate issues but also intertwined

First off, don't wait another day. The "I'll start approaching when I get a 6 pack" is a lie you're telling yourself. You need to start taking action today, not if or when this or that happens. Don't beat yourself up, you're not the first person to go down this line of rationalizations. In fact, I have a close friend who constantly does this sort of thing. And today, he's exactly where he was in the same place where he was at 5 years ago. Because, excuses breed more excuses and action breeds more action

Adopt the right view when it comes to sexual market value. And the right view is what I'm about to tell you right now.
Yes, looks absolutely do matter. So does status. So does style. So does all that shit. However, game also matters. Also, the girl's type matters.

So what should you do? Focus on both maximizing looks and developing good game. In order to do the latter, you need to approach. Thus, you should be approaching while you're working on your six pack. I also recommend progressive deconditioning. If group sets make you largely uncomfortable, then start out by approaching girls who are by themselves. Then after doing that for a week, approach 2 sets. and so on....
