my next step?

so i've just ordered the si rear sway bar. any suggestions on what my next step is, please? so far, what i really want to get are the front lower tie bar and a rear strut bar. since i dont want to get strut bars that have pivot points, i want to get either neuspeed or mugen(but god knows they are all expensive). or maybe i can install a rollcage? with limited cash, i really dont know what i should do next.
