Intake, exhaust, ECU are about the only things that will be fairly straightforward and easy.

Make sure your suspension (and all associated bushings) are in good shape.
Renovate your brakes and put on the best tires you can afford.

Then learn to drive it well.

Making "more power" with an internally stock NA engine won't gain you nearly as much as making sure you can actually apply and maintain the power you have now.
