Need help prioritizing my next mods

I know what i want done to my car, but i dont know what order i want it done in and i would like some help putting each mod in it's place. here is my list, i know they vary in price, so keep that in mind. if one is cheap and i can afford to get it before i start saving for another thing, put it first.

1. Tubular front end (coilovers, k-member, a-arms, cc's)
2. aluminum driveshaft w/ loop
3. 5 lug conversion (strange axles, auburn diff 31sp, cobra rotors, etc)
4. Tremec 3550 (i have a T-5Z now, but i dont trust it)
5. Drag race rear swaybar
6. 50/50 rear shocks
7. double adj. upper control arms
8. aeromotive fuel system

My motor right now is a 306ci on nitrous putting about 500 to the ground. I plan on keeping this motor for a year or so until i can put together a 331 with a T76 on it. I kinda want the chasis to be ready for it so i dont drop the motor in and have other weak links. but that motor isnt happening for a while, so i want to get the things most beneficial to me now.

so the 5 lug swap first huh... sweet, prostars will look sooooo much better on my car then draglites

well i cant really build the rearend up w/o doing a 5lug. if i build the rearend up ill get a 31spline diff, which i need 31 spline axles for. but if i dont do the front 5 lug yet, then im not gonna do the back 5 lug, so ill have to buy 4 lug 31 splines for the back. when im ready to do the 5 lug and everything, ill need to get another set of axles for the rear.
