Leverage Browser Caching

Leverage Browser Caching
Though my first byte time is awful, I've been on the leverage browser caching war path for months now and need to get serious. It'll probably be obvious, I'm not a pro at this stuff.

I use W3TC and WP Minify. I have four .htaccess files - 1 root, 2 W3TC, 1 WP Minify. My gut is the root file is a car crash, after 1.5 years of trying to learn some things...

AddHandler application/x-httpd-php5s .php
### BEGIN .htaccess
#Begin gzip and deflate
<IfModule mod_deflate.c>
AddOutputFilterByType DEFLATE text/html text/css application/x-javascript text/plain text/xml image/x-icon
</IfModule>

# Set Cache-Control and Expires headers
<filesMatch "\\.(ico|pdf|flv|jpg|jpeg|png|gif|swf|mp3|mp4)$">
Header set Cache-Control "max-age=2592000, private"
Header set Expires "Sun, 17 July 2011 20:00:00 GMT"
</filesMatch>
<filesMatch "\\.(css|css.gz)$">
Header set Cache-Control "max-age=604800, private"
</filesMatch>
<filesMatch "\\.(js|js.gz)$">
Header set Cache-Control "max-age=604800, private"
</filesMatch>
<filesMatch "\\.(xml|txt)$">
Header set Cache-Control "max-age=216000, private, must-revalidate"
</filesMatch>
<filesMatch "\\.(html|htm)$">
Header set Cache-Control "max-age=7200, private, must-revalidate"
</filesMatch>

Any initial guidance re the mess I'm in would be appreciated. Again, I'm thinking my .htaccess file(s) may be the issue.

Thank You...

RE: Leverage Browser Caching
Have you compared to a clean new wordpress .htaccess? I'd probably just start from scratch (kind of like nuking and re-installing windows when it gets crufty). W3TC should be able to configure the browser caching for you so you shouldn't need to hand-edit the .htaccess

So I did it and managed not to blow-up my site. Put in a clean .htaccess file with the WP minimum stuff. Hopefully, W3TC will fill in the blanks and I'll see how I do with page speed, etc.

Thank you so much for the attention...
