You would be fine with just that...
But, you can also add some coilovers or you could use a leveling kit on top of the spindle lift for more lift.
For the rear, you can add a block and deaverpack. If you go over 2" of lift in the rear, you'll need new shocks.
Give PRG a call.
Since it seems you are on a budget, I would but this package right here...it's perfect and is a nice bundle of what you NEED.
