Well for starters, you're going to need a custom chip burned. You'll also wish you had a Quaife LSD for peace of mind and a high performance clutch. A free(er) flowing exhaust would really help, and you'll want to get an open element air filter instead of the K&N drop in. Other than that, you may want to invest in some descent tires because even hitting it in 2nd gear is going to cause you some traction issues.
Where are you getting a deal on the VCN2000 kit? Is it a used kit, and if so, who is it from? There was a kit going around a while back that people were having problems with(ie: missing parts, crushed nitrous lines) so I hope you don't end up with that kit. If through a supplier, where is it and how much are you paying?
