If you're goal is to squeeze every last drop from the car, sure go ahead. Or if you want the sound that comes with it. But these aren't "must have" items to make power.
Here's how i would "categorize" the bolt ons and rank in order they should be done.

1. CP - most important for reliability
2. IC - most important for consistent performance/power delivery, and to a certain extent, safety and peak power
3. DP - only mod that really provides direct bolt on power gains all else being equal
4. inlet - most tangible improvement in drivability, when coupled with intake optimization
5. intake (aftermarket/open element) - personally would not do, mostly noise
