How to setup a product associated with a node ? but without choose again and again

Hi:
I wanna solve this problem. I have a product associated with a node. I'm sending you all the pictures it describes the situation.
1.- When i have made an order and It uses a view in the settings It can be created a new node (picture uc_checkout_01.jpg) but when it doesn't use a view It can't .
2.- I have made the association but when I have an order and I create a new node I need to choose again a Product (picture uc_checkout_04.jpg). How can I omit this step ?
3.- After I have choosed a product and when I write the data in the new node I have to choose again the product (because it's refered). How can I set the product selected in the last step ? or How can I omit the last step and set the product with the one choosed in the order ?
Thank you for your help.
