Uprated ARB's and springs IMHO.
the ARBs will transform the handling, and the springs will make the look better and help with handling.
then uprate to coilovers later.
I cant really pm you a list as it all depends really.
as for your plans, 2 questions.
why got to all the effort of changing internals if your going to run 250-300?
Why do you want to keep VVTi?
The only explaination to me seems to be the alarm install.
you sure they didnt move the door car because from my knowledge of the Lexus system the drivers door area is the best place to attach to a lot of the wires required for fiting an alarm etc.
Couriers like parcelmonkey or parcel2go are good. Ive shipped a charger using them before.
As for removal its pretty simple as its all external to the engine. This is provided AJ has all the standard bits to refit?
If you search this section theres loads of info about charging.
i may have instructions somewhere, pm me your email address and ill dig them out.
you can do it yourself in about 6 hours with a few spanners and a socket set (and a drill for 2 holes)
