Congratulations! I also have a deposit on my first Bengal kitten that I will be picking up at the end of April.
As I have virtually no first hand experience with the breed myself, I can't really offer much advice. However, I can share some of the resources that I have found in the past couple of months.
First of all, while you're here, there is a sticky thread in another forum on this board that covers the basics of the bengal breed:
<a href='http://www.bengalcatforums.com/forums//index.php?showtopic=10' target='_blank'>The Characterisitics of the Bengal Cat</a>
Another good info resource is The International Bengal Cat Society:

The TICA breed standard in case you want to know what makes a "show quality" Bengal:

And of course, the best way to get specific answers pertinent to your kitten is to ask your breeder.
