My Privacy Plan by Ben Matthews looks like a good start: http://benrmatthews.com/2013/06/my-privacy-plan/
What are your recommendations? Bonus marks if it's relatively simple and fast to implement.
Then use some form of anonymous payment for anything you buy.
Ensure all of your browsing is done through Tor and/or a VPN.
Don't cache anything, just in case you get raided.
Also, always use a PC in the dark. It works. Trust me.
You connect to the internet you're going through the USA even if the company you're dealing with is based in some other place. For example, I just ran a tracert on a connection to a college located in the same city I am in, it goes through New York State before hitting a data centre in the UK.
You can install Ubuntu, use AOSP on your phone, and use Firefox for your browser. But as soon as you connect to any service, including Hacker News, there is a good chance you're being spied upon.
If you want to avoid the dragnet then I'd stick to obscure sites and services (i.e. smaller providers) since the NSA likely hasn't taken the time to spy on each and every one. Also online game's interplay chat might be somewhat spy free (relative to other IM services anyway).
