About To Sign Up With Party

I know it has been discussed countless times but looking for a clear cut answer.
I will be switching to Party and looking for the best route for added $$$. 8-10k hands a month 2k nl tables.

Im assuming the vip program is the best way to go. Is it best to deal with party direct or are there "affiliates" to use?

Should one negotiate ahead of time or just open an account, play hands, then discuss?

thanks
