Adding tabbed content in D7
It sounds like you are looking for something like the Quicktabs module. I have an implementation here: http://gamebah.com/gsqrd/node/24. 

You  will make a block for each tab (Twitter, Facebook, Feedback, etc.) and then using Quicktabs (under Admin > Structure > Quicktabs) you can add the blocks to a new tab set. It is very self explanatory but if you need more help, don't hesitate to ask.
