Also, I would need 68 which is English Threading, correct?
68mm is the width of the bottom bracket shell for a standard English BB, so, correct.
The bottom bracket type needs to match your crank. If it's the latest series 105 crank, you need the parts for the hollow spindle. A sealed cartridge BB is probably the older Octalink type, which is for a different crank.
It's helpful if you include URL's when you're asking about compatibility. For instance, this crank:

takes this BB:

(or Ultegra or Dura-Ace)
not this:
