I vote for LTs/tune and then work on suspenson to get it all to the ground. Drop the springs in favor for some coilovers. Make sure to do some trailng arms and cradle bushings. Rear end bushings if you can afford it as well.

You will eventually get used to the power that will be doing for you and in a year or two you step up to the cam to feed your HP hunger again. If you do the cam now you'll have to feed that hunger with a supercharger or something.
