Use Google Fonts for hundreds of free, open-source fonts optimized for the web. Font Squirrel Generator for fonts you have license for using as web fonts. Fontspring @font-face syntax is also the most bullet-proof way of serving web fonts. You do not need polyfills - just fonts in several formats; WOFF is preferred, followed by TTF and then EOT.
Also, don't use solutions like sIFR or Cufon anymore, as they can cause accessibility and performance problems.
