Didn't check through 11 pages worth of content but easist way to list your eBay auctions on your own site is with their Merchant Kit.
You cannot get rid of the eBay banner but you can customize the fields you want to display and get it as narrow as ~ 126px wide.
There's also the Editor Kit which offers a bit more customization. That one is basically for people who want to get referral sales off their website but it has all functionality of Merchant Kit and then some.
