Modify & Import an OS Commerce CSV file into my website

I have an OS Commerce website. I have never used the easy populate function before. I have a csv with 8500 products on it that i want to import. I have made a test of just 10 products. I cannot quite get the import to work, every time i try it i end up creating new categories and my product images do not import. I also do not know how to assign 2 categories to a product and more than 1 image to a product. I would also like to add the RRP but i do not think i have the plug in installed for this. I have attached a sample of 10 products from my primary database and also the test import file i made. If somebody could edit the import file and make these 10 work i am pretty certain i can copy the method and do the rest myself.
