I'm looking to get a smarty but I'm wanting to get all my ducks in a row before I do anything. I know I need guages(which are coming first), but what else am I gonna need to get the most out of a Smarty? I'm talking like cp3 pump enhancements, lift pump, boost fooler and what is the best module/box/etc to stack it with. I know I will need a clutch and some more air also(twins are in the future).

 

guages you are already dealing with.
an aux lift pump(since yours is in the tank) will help alot. like a booster, in tandem with the stocker.
either a boost fooler, or a module that already does boost fooling(most do).
some of the smarty programs take care of boost fooling for you.
cp3 will be ok until you want more than 550hp and get larger injectors.
clutch is going to quickly hate you.
and your egts will get hot, so you'll need a turbo.
you have already listed these things, so you are well off from the start.
Get R Done!
