first off what exactly are you trying to do?
either way i can tell you you dont need a new crankshaft.
well im guessing your going n/a since your keeping your header (although you could be supercharging)
and no you dont need to change anything youve got.
if your going n/a with a bigger cam, depending on the cam you may or may not need new springs and retainers.
cam gears would be nice
if your doing bottom end work yu might as well replace the bearings, even though the car is a year old new is better then a year old, especially since your obviously gonna be reving a lot higher then you normally would have. you might wanna think about using arp shit to fasten down the head to, as well as a better head gasket.
a lightened flywheel helps, as does a better clutch
a bigger throttle body, port and polished head and intake manifold or euro r manifold as well as a valve job would help complement the cams quite nicely.
and one last thing
dont forget about the fuel
all that air wil require more fuel, start thinking about fuel upgrades before anything. now might also be the time to do the obd1 conversion or the ecu bypass like the ntpog have discovered.

cant think of anything else now but im sure someone else will
