You don't have to remove the Throttle Body! So don't worry about that gasket. And you want to remove air intake duct just to give you room to work, the resonater is pretty much part of it. And as far as the pipes go, you just need to unbolt them from the exhaust manifold .They don't need to be completelty removed. And as far as how hard it is , is all depends on how badly the bolts/nuts are seized in the ex. manifold and head. I would spray them with Cyclo Penetrating oil or PB Blaster for a few days before I did the job. You don't want one of those breaking in the head.
