Welcome to Namepros niftystats :D. I would recommend visiting freshdrop.net. They have a list of expiring domains and you can sort the lists based on pagerank, backlinks, traffic etc. You will pick up how to use it fairly quickly.
You can get some nice domains at TDNAM that have traffic. This is because there is still a page hosted on the domain before you get it. When a domain drops and has no content it can lose traffic and links quickly. Their traffic numbers are not very accurate, but they give you an idea of how much traffic it will be getting.
