You asked, "What are some things that I must check out while in vegas?"
Be sure to check out of your hotel before you leave...
Other than that, any Cirque du Soleil show that you haven't seen before is worth checking out, and for Surf and Turf (Prime Rib with 2 lb. Lobster), go to Alan Alberts restaurant.
If you want to drop a bundle on the best meal of your life (while looking at an original Picasso painting), then Picasso's in the Bellagio is awesome.
For entertainment, check the shows online in advance and then call the concierge service at the hotel you will be staying out to secure good tickets.
If you want to drag your dick in the dirt, there are many ways to part with your money that way...if you are into strip joints, remember that generally the more you want to drink the less flesh you will see...and if it's hookers you are looking for, well that's illegal in Las Vegas...
Have fun and keep repeating, what happens in Vegas stays in Vegas (make that your mantra).
