Having been in a couple of "Armed Encounters" I can honestly say, the pee is no big deal. I do respect you for admitting to it though. I've peed, puked, hypervenilated and all sorts of other crap.

I'm glad you and your gf are OK, that's the most important thing. Now comes the learning session.
First thing, I carry the biggest gun I can conceal because I shoot it better than I do a "mousegun". Off Duty I favor revolvers, carry an issued "bottomfeeder" at work. I have on my person either a S&W N-Frame 45 ACP Revolver with a 4" Barrel or a 3" .357 Magnum. I also have a "mousegun" that I carry as a BUG. That's my S&W 442. If I have to carry a "bottomfeeder" off duty it's my Glock 19 and either the 442 or a Kahr PM9.
Someone else already mentioned the cursing, and I will concur with them. Give short verbal commands without cursing. Cursing takes too much time and you don't want this to sound like a fight between "willing combatants".
I would also encourage you to consider lateral movement when you draw, so that you get off the line of attack. When I'm at the range I will take one step sideways as I'm drawing, if not more steps. I also look for "cover". Cover is defined as something that will stop incoming rounds.
All in all it sounds like you did a good job. You came home alive, that's what's important.
