welcom to airsoft. Let me start off by saying anything from CanTire is crap. When I started airsofting i bought a set from wally-mart (same garbage) and regret wasting my money. Do yourself a favour, fill in your details like location and such and take the time to read some of the FAQs available in the forum section (I found it very helpful).
As far as a gun is concerned, I wouldn't waste any money on that junk. Attend some of the games and post a request for a gun "rental". That way you don't have a bad experience because you were completely out gunned. (I was out shot 10 to 1 with my wally junk)
Save your money, get yourself age verified (Assuming you're 18+) and many better solutions will be available.
