How to apply effect to more than one clip at once

Question

Is there a way to select a number of clips and apply an effect (like three-way color correction) to all clips at once? Right now I can only double-click on one clip and touch up one at a time.
On a similar note, my photo editing software has something called "tone curve adjustment" which is the best device I've used for adding light to a dark image without losing integrity and quality. Any idea what the closest thing to that would be in FCP? Adding brightness flattens out the image and makes it milky and grainy. Could it be that I should avoid whites and middles and concentrate on black and saturation?
Thanks.

Answer 1

Question 1:
Copy the clip with the color correction.
Select all the target clips.
Control-click on the selected clips and choose "Paste Attributes".
In dialog box, select "Audio Filters"
If you want to keep working the CC later,
it might be easier to nest the clips.
Option-double-click on the nested clips
and apply global effects to all of them at once.
Question 2:
This is something like Photoshop's Curves with the menu set to RGB?
Working with dark footage, I often use the Color Corrector 3-Way
and boost the Mids level a bit. If that pushes the Whites too much,
pull them down.
I often "crush the blacks" by using a second 3-way, using Limit Effect
with Luma only, selecting only the darkest parts of the image,
and pulling the Blacks down to minimum. That makes the whole image
more dramtic, and reduces the effect of noise when you compress it
for DVD or web delivery.
