1. The most important thing about buying a new bike is to make sure it fits. The only way you'll know if the bike is right for you is to size up the bike and make sure that the bike's geometry matches your body's geometry. Ask questions and do some research.

2. If possible, try to find a shop that will let you demo the bike on real dirt. Five minutes in a parking lot won't cut it. You wouldn't buy a car without a real world test drive, and a bike should be no different.
3. Don't belive the hype. Just because your favorite rider or best friend rides a certain bike, that doesn't mean that's the best one for you. Have an open mind and be realistic about your needs and ability.

    Standover and top tube measurements of a bike?

    I used the bike fit calculator off of Competitive Cyclist Fit Calculator - Competitive Cyclist and got my standover height and top tube length. Now, how do I find these measurements on the bike. What I've found seems like mumbo jumbo to me. Providing sites with pics would help.

    Here's an example from Giant:

    I see that they don't show "H" for standover in the diagram but it's normally the height of the top tube about 12" in front of the seatpost. It would be right around where the "D" begins in the picture.

    ^^ That chart above should help quite a bit. Here is another at Trek Trek Bicycle

    Usually if you dig into the Manufacturers site to the bike you want there will be an area for specs or geometry. Specialized doesn't have a picture of the bike, but they do have the geometry listed for each model associated to each size. Here's an example:
