Image Transformations and Rocket Loader

Hello!

I activated Rocket Loader. Will this help the site to be faster?
I have the Pro version.

Also if I activate Image Transformations the images will be stored on my server and cloudflare will simply take them, resulting in the images loading faster?
After activation, do I need to do something in wordpress? or simply the only thing I have to do is to activate it?

Thanks in advance!
