what do i need for the track

i need help figuring what i need as far as saftey equipment for the track. i have looked at the rules and i belive i will fall in the 11-11.99. i am planning a 6 point roll bar weld in and a 5 point harness but i am having trouble ordering what i need.
more than likely it will be from summit racing.
so if i order the roll bar main loop and strut kit,do i need the harness bar too??
does the bolt in 5 point harness bolt to the floor and how does it attach to bar??
and do i need a racing seat that is bolted to the bar?? or can i just use my stock seat.
what is a metal screw in valve stem??will it work with my cobra rims.
i have a driveshaft saftey loop and my nos bottle vented outside (i have a hb) and the car is very clean and in great shape. any help would be great as i have to bring my car about 700 miles to the closest track so i don't want to only get one run in!!! my best to date is 12.56 but i have allot of work done since then.

allso how do i know what rack and pinion i need? online they show many diffrent types from the same manufacturer. how do i narrow it down??

it helped greatly,thank you very much. i have a short summer where i live and a long haul to the track so i have to make the most of it. i figure if i don't need it going overboard on saftey is not a bad thing.

this where i got the info from.http://my5ltr.tripod.com/NHRArules.html

she is definatly trailered!! and you should see what freezing and thawing does to a highway. gave me a good excuse to buy my f250 deisel. but in northern canada you gotta make the most out of your summers.
