What would be the benefit of doing this? Is it really worth the work that needs to be done to install these.

 

It removes some of the slop from the stock bushing and makes your suspension a little more responsive at the cost of some additional NVH, don't expect a huge difference. Some of the bushings need a press to be installed correctly. Whether it is worth it depends on the individual and their needs. Most people don't replace all the bushings but select ones.

 

Like was mentioned it will tighten up the feel of the car a little bit, at the expense of a little added noise and vibration, probly not too noticable.

I have heard that the precision steering kit (bushings) work well. These are included with the package.

FWIW, I'm going to be ordering this package shortly along with the front roll center adjustment kit.

 

Will all of these bushing upgrades make the car faster?

 

Yes, it will make the car handle better as a result of the suspension being more predictable. The deflection in the rubber bushings can cause some binding.

 

yes, yes and more yes

 

Which specific bushings provide the most benefit, in your opinion? I changed my swaybar bushings, but am undecided which ones to do next. Also, are the swaybar endlinks from Perrin worth it?

 

Definitely the trailing arm bushings, and the sway-bar bushings were a good choice.

 

What exactly do the trailing arm bushing change in the handling? Are they particularly prone to distortion stock? Is it a difference you can feel right away, or very subtle?

 

Most likely you will feel the difference in mental handling.

 

As Czubaka said swaybar and rear trailing arm bushings are good ones. Some people also do the rear bumpsteer kit. IMHO, Perrin endlinks are worth it only when your suspension is lowered ...

 

Bumpsteer kit and rear trailing arm bushings, and rear lower shock bushing.

Much bigger difference if your EVO is getting older....but still a nice upgrade.
