Couple of things I haven't seen mentioned that could save you some money. The first being the Machined Lower Intake Manifold, you don't need that with the Short Stack Intercooler. The next being the Ported Supercharger, its way too soon in my opinion to be looking at that as a mod for your setup. That more for when your going smaller then a 3.0 pulley an outlet temps on the blower are a serious concern because your pushing the stock M90 so far past its original efficiency range. An the TB is more or less just to match the blower inlet. With the larger ones you can feel a difference in throttle response but your not getting any faster till your car needs more air then the stocker can supply.
If I were you I would do the Rockers (modified stock 1.9) an the 3.4 next an then spend some time tuning it in, probably have to add a little fuel to quench any little blips of knock. You should also be in the 13's with an equal launch, if you managed a 14.4 with what you have now.
By then the mod bug will have bitten an you will rethink your entire plans an goals for the car. But until then enjoy your goal.
