Also, you have a steel frame, steel fork, beefy MTB stem, and heavy old-school saddle. Spending lots of money on "light" wheels won't do much to lighten that bike...not that you should. Just get some solid wheels for under $200 and ride and have fun.
When you want a lighter bike, start with an aluminum frame and carbon fork.
I believe its a 53cm, fits me nice at 6ft with short legs
Dude, if that bike is a 53, it's waaaaay to small for you. 55 is too small for you. If you are 6' tall with short legs and longer torso (that's how I am but I'm 6'1) then 57 or maybe even 58cm is appropriate for you.
