Difficult way for add new products

I use Quantity Discounts and Image Handler 2.
I have to insert over 3000 products in my zancard shop.
For every product i have to insert it, after that i am going in proce manager to add quantity discounts, after that i have to go to image handler to add more photos and back again.
It is a better way to do that? It is possible to have it all in one add-product-page or something like that?
Thank you

EZ populate would help you greatly

EZ populate?Where is that? I see only Admin/Tools/EZ pages .... but i dont understand what i do there for what i need. That is for the pages but not for the admin

Ok, i found easy populate. Thank you. Sorry, i dont knew it....
The problem still exists.
Easy populate, dont have anything about the quantity discounts and the 2nd,3st (etc) images in a product.
So, i must (still) add one product, after i have to go in Price Manager to add the quantity discounts, and after that i go to Image Handler to add the other images...
Easy Populate its good only for adding products with the default details (one image, one price)
Any idea?
I wanted something like one-page-add-new-product. In the basic page with the product details (add new product), adding the quantity discounts and the other images and ... click and add! (I am dreaming???)
