I think most of the guys here have covered most of the important parts and figures as well as who to go to.
I've got similar mod's to what you have planned and Beeble has managed to tweak my car to 182kw atw.
I'd suggest skipping the boost pill and go to 3 port as Mitch said. Also, for the intercooler swap, definitely change the pipes and don't use the stock silicon ones. I got the Ultimate racing ones (upper and lower) and it does make a bit of a difference.
I know this isnt a power mod, but I'd also recommend getting a whiteline rear sway bar. Swapped mine over and noticed a change straight off.
