First thing I would do personally is to set out a plan/goal/finance.
Then I'd plan it out as to how soon the amount of money can be shelled out.
Assuming everything was ok, I'd then research the suspension for the type of driving I'd be doing. Road-racing vs drag racing vs street driving. Buy the suspension from one company as a package deal. Not forgetting tires being the more important part of the equation.

Having set the foundation of the vehicle and knowing what kind of driving, I'd then turn my researching powers to either forced induction or naturally aspirated setups.
I'm sure the more experienced guys can help you out more once you've decided upon a specific route.
