YSlow, FIREBUG Plugin

Other Tips:
- Use a CDN for serving common library code. Do you really need to host Jquery yourself? (side-rant, do you really need jquery at all?)
- CACHE ALL THE THINGS
- The whole bandwidth can be reduced by about two thirds if you enabled gzip compression on your server (or even better, implement SPDY, but that's a newer technology with less of a community).
- Take a look on http://caniuse.com - there are a lot of CSS technologies that are supported in modern browsers without the need for -webkit or -moz, which could save a fortune of kebabbobytes.
