I currently run an ecommerce store using Magento CE version 184.108.40.206. There have been many releases that each have had a number of fixes and new issues since then. I'm in the process of planning an upgrade and will be rolling out 5-6 new sites that will each be running on their own domain names, but will be using the same codebase and back-end as my main site. I'd like to know what version the community recommends upgrading my main site to prior to this roll-out? Should I go all the way to 220.127.116.11 or should I stop somewhere before that?

Yes you should always upgrade to the latest stable version for security, features, and performance.
