Answer 1

If you add &responseencoding=JSON to your URL you will get the response as JSON according to docs

UPDATE Working example. What I've done is that I changed to dataType:'jsonp' added jsonp:'callbackname'. Because jQuery by default calls the callback parameter callback, but eBay expect it to be called callbackname. What you have to do is add your parameters to the data map. Make sure you use the correct parameter names, check the docs and use the URL method not the header method. Hope this helps.
