1) The current version doesn't have a currency indicator, so it would be changed in the templates.
2) Making the images link for an affiliate link would also require a change to the templates as the only link we have enabled is a generic one to dealtime.com which uses keywords generated from the product title.
3) There is a bulk add feature, but it may or may not handle the data feed you are talking about. It's more of a quick way to upload images of items that can then be edited to add descriptions/titles, etc.
Please do not PM me for support or sales questions. Thank you for your understanding.
