Harris on "[Plugin: W3 Total Cache] Add Expires headers / Make fewer HTTP requests"

I'm oblivious to these 2. Can't seem to reduce it.

Make fewer HTTP requests
Add Expires headers

Yslow on http://gtmetrix.com is 80% my page speed is 96%.

I ipen the .htaccess file and it show the expires 31536000

Is there way to do this in W3 or not.
