configuring VS2008 for cuda c 4.1

I am trying to code cuda c using VS 2008, but not able to configure VS2008 appropriately. Could anyone take me through the necessary step? And, I read somewhere that nvidia NSisght should be used for cuda c in VS 2008. I would like to know about NSight also…
Thanks in advance

Dear txbob,
thank you for your advice. I have one more doubt that what exactly is nsight and is it mandatory for using cuda in Visual studio??
