I'm not sure of the Dorman part number, but just make sure you get the "NPI" or "Non Performance Improved" model. The PI model can be used but requires modification of other parts. The Dorman NPI intake is a drop in direct replacement. Most people I talk to just buy them from eBay.

As for the fuel rails, there are special tools to remove them. To do the intake swap, you don't have to remove them, just lay the fuel rail off to the side.
