yeah the amount of things i can do with my build are pretty impressive. I'm still in the process of learning everything that I can do. So far i've made good use many of my options, but I'm sure there's more to it. A note on the quick draw though, the challenge is like 3 and I roll 10 + dice, i can't fail to quick draw. So even on turn one I can free action quick draw and shoot as part of the same action, then shoot again, then do something else with a simple action. But your chain of actions is just as good really, more a question of situation.
You can't quickdraw+shoot as a Free action. It's a simple action. (So you do: Simple Action: Quickdraw+Shoot, Free Action (call shot, take aim, speak), Simple Action shoot.)
The benefit of quickdraw is that you'd otherwise waste a Simple action just to draw the gun, so you'd only get off one shot in that IP instead of two.
Shooting 3 times is impossible I'm afraid.
The "Ready a weapon as a free action" isn't really valuable if you're a character specialized in pistols, because like you said, getting the 2 or 3 dice to quickdraw is trivial anyway.
