Price Books - List price = Unit Price option?

Price Books - List price = Unit Price option?

Hello,

I have thousands of different products and I only need one price book with NO pricing model. 

Is it possible to have a single standard Price Book that I can quickly and easily add ALL of my 10,000+ products to without manually having to click add to each page of 100 products?

Is it also possible to have the list price automatically sync to the unit price?
