sit/stand, cleaning, exact shot..lots of questions

[psebow]

Sit/Stand - So, I've been out a few times n my stands and was wondering should I be standing when I want to take a shot or is it okay to sit?  I am a rookie, and just want to learn all the tricks...standing makes a lot of noise...but can limit my shot?  Any advice?

Cleaning - I have read up on all the cleaning techniques for deer...never having shot a deer or gutted one I am not quite sure what I am getting myself into...I have a good knife, gloves and a good idea on how to gut it...any advice?

Okay, basic question...I know I want to hit the heart and both lungs on a broad side shot...is that right behind the shoulder?  I just want to make sure I make the best kill shot as to make it a quick and humane death.

I might sound like a "major" rookie but I do know a little about the outdoors and am an avid ice fisherman and pheasant hunter...I just love the whole Bow sport...I shot my father in-laws bow once (yes, only once)...and I made my mind up...I am getting a bow and taking a deer with it.  I am so excited.  Thanks for the input..

You can google deer gutting and find lots of stuff. Here is one link that is pretty good.
