You actually DO need commandLink's to be nested inside of a form. MyFaces has a convenience where it will create a dummy form for commandLink's that aren't inside of a form, but this is not to spec. What I was saying is that you don't need SEPARATE forms for all 3 commandLinks. You can use one form for everything, your commandLinks and your data.
I know how you feel. 6 months ago, I was doing the same thing. Now, I'm getting close to expert level. MyFaces is really awesome, just stick with it!
