I'd add a new crank pulley, OEM or a good aftermarket DAMPED one, and a new drive belts(alternator etc). No use having to do this later on when the pulley seperates.
another simple, low cost but very effective boost controller is one from boostvalve.com, but the ones you list are good too.
use the big filter for oil.
and when drilling and tapping, 2 things. do it with the engine cold but running, this way crap is blown out. and put some thick grease on your drill and tap, this will help keep it from falling inwards. shut the engine off when you are not actually drilling and tapping so the manifold stays cold. Maybe even drill out 90% of the hole with the engine off, just don't go thru, and have some grease on your bit.
/edit/ forgot some things, sorry.
balance shafts have to be removed, not just disconnected. One will still be spinning and cause worse vibrations than if they are not there at all.
I second the NGK plugs and wires, and if your O2 sensor is old, get an NTK one of those too.
stay away from Dexcool, corrosive and crappy. Stick to a good quality green coolant. Or if you plan on hitting Mission or other racetrack, run just water and Water Wetter till the end of the season and then put in antifreeze.
For tires, another low cost but good tire is Khumos replacement for thier tried and true Ecxta 712, its called the SPX and is a good tire for the money.
