Re: MyFaces equivalent of using JSTL 'if' and choose/when within JSF compoents?

As Martin said, each component has a rendered attribute.
If you want to conditionally render several elements, you'd set it on
an enclosing PanelGroup or PanelGrid component.

Iteration is a separate issue.
You could do this with a DataTable or DataList, I suppose.

 I'm a bit confused on how this is handled with MyFaces.

yes, use the MyFaces dataList:

Yes, generally, you want the JSF component itself to do the implicit
iteration; one doesn't explicitly iterate in the JSF page.

usually you use the rendered=#{backingBean.someMethodReturnsBoolean}
to determine if a certain area of the UI should be shown or not.
