Hi everyone,
Just thought I'd post an update and let you all know the part I ordered, and finally got today works!
We've got hot water and so my wife, 5 kids and I thank you all for the prompt and accurate replies.
I thought I'd upload a few photos showing what we've got going on now. It wasn't as daunting of a task as I originally built it up to be.
Fieyorrrrrr!
A couple things I did while installing:
* Bent the input pipe a bit with my hand to make sure it wasn't putting too much strain on the new valve body.
* Blew out the orifice that attached to the out-flow side of the valve. I looked through it and there was a bunch of scum inside, once I blew it out it was much larger.
Thank you all again for the help and suggestions. If there is anything you see in the pictures or notes above that is incorrect, feel free to let me know :D

Howdy,
Nice install..........looks good.
Glad it is making hot water for you and family
Couple of things to improve function
*Gas orifice...you blew it out---hopefully just by blowing on it and NOT using high pressure air hose (or poke anything thru hole)
To properly clean.....remove it, soak it in alcohol and then pucker up and blow it dry. Poking/high pressure air can damage orifice
*Burner tube.......hopefully it is still aligned so gas flows down center of tube where it creates a venturi affect to pull air in thru air shutter and then properly mixing air/gas.
If not.gas bounces down inside of tube and air doesn't get properly mixed upsetting air/fuel ratio
*Burner flame.......WAY too much YELLOW. Flame should be strong BLUE with tinges of yellow at tips.
Yours could just be a 'rich fuel' condition and opening the air shutter a bit more may correct it. Shutter looks a bit to closed off.
If not....reclean orifice and burner tube (small bottle brush down thru tube)
Correct that flame and ENJOY!

OH yeah.....that petcock?
Did you at least open/drain/flush tank when gas valve was removed??
Really should be a NYLON plug.....:B
