You are going in the right direction with all your upgrades, not a lot to add.....don't scrimp on safety items and your driving gear....before each track day put your car on jackstands and go over every nut and bolt you can get to,check tie rods and suspension components for wear/play,check all your fluids and while under the car look for any leaks of anything.......
Drive to YOUR comfortable limits and safety level, as you get more seat time, you'll get faster and smoother......Smooth IS fast....get someone (maybe Dan) to ride along with you and observe and they can give you tips about what your doing right and wrong,you'll be suprised at what changing up your line a little here and there can do in some corners........
Ask Dan (yes, I know him) about turn 9 and cold tires!!!!!!!
Get on the track and have fun/fun/fun..........
