I Second Ghettopop, the motorcraft/autolites are fine. gears will get you the best bang for the buck. But dont forget the freebies: timing, airbox silencer, etc.
As far as upgrading, do it in stages. All motor may go fast, but theres more to it. Do some of the engine mods, but then look at suspension/drivetrain. Subframes first, then maybe a control arm setup.
More engine mods, then maybe an underhood brace and brakes, etc. You want the car to be designed as a total package.
To quote 5.0:
"Again this can get quite expensive, but a 200 hp car can beat an 800 hp car if it is set up right. "
All the power in the world doesent help if you cant get it to the ground.

Just my .02
