Working with what you got...I would just recommend mounting the right front and left speakers lower and more symmetrical (maybe set them to center of your tv, height-wise). And a little cable management. You can get the wire runners at home-depot or Ikea...I'm using those for my rear surrounds if you wanna see what i am talking about.
When you are ready to graduate to Lossless Audio ask the guys on this site for advice...they will not steer you wrong
BTW: Petrie is a cutie
And one question: Do you have 5.1?
