Bottom ends, all those you listed are reputable.
Injectors, probably want to go for the Bosch 1600cc (Indy Blues?) so you have enough headroom for E85.
Intake, probably best to go with GReddy as the Plasmaman unit, while nice, bolts to the top of the stock runners which may causes clashing issues (stock plenum on my 30 in my 32gtst, I couldn't fit the strut brace back on).
Exhaust manifold, I have a 6boost made for my application, nice bit of gear. There are a couple of other good local manufacturers out there but can't remember their names (XTM? etc)
