Don't waste your money on a TB spacer. While it may work on carborated applicatoins, it really doesn't do anything for a fuel injected engine. Plus there are serious clearance issues with the CnL with a TB spacer. Trust me... I too fell for the hype and bought one awhile back (it's now sitting on a shelf).
I would come very close to these same numbers. I did install a throttle body sapcer as well, and felt no significant improvement, so I removed it. I will have say, learn from the expereince of the poor fools (me included) who bought a TB spacer. I grant, many will argue about the throttle body, but I agree with stlwagon, it will give you 5-8 hp (as much as 10 if you believe the manufacturer) but more precesiely, it does give you a better throttle response.
I have added much of what you are looking to add (brand names not with standing) and you will feel a difference with all of these mods together.
