Auction site such as ebay are useful for driving traffic, but you need to remember that unless you are an established seller you are going to need to offer something special, the days of being guaranteed to make money on auction sites are sadly gone unless you are selling something unique, or unavailable elsewhere, you could use it to sell lossleaders, and to gain traffic by introducing people to your website in the process , ie follow up mails and mail signatures containing your site address , but you would have to be preapared not to make money on the sales, I've used ebay this way in the past with a varying amount of success.
Again the best way to drive traffic to any site is to have established a target market, ideally this should have been done before deciding which products to sell, as with anything getting traffic to your website is actually relatively easy, its converting that traffic into sales that is the tricky bit, it's made easier if the traffic you are getting is actually looking to buy your products
