Revit :: Labeling Parts In 2012?

I wanted to know how people are labeling or taging the "parts" of their construction, like walls.  I want to be able to tag the parts so that a description of the part is pulled from the material so a change to the material affects all lables and tags.
 
The 2 problems I am running into

1. in a 3D mode I cannot use a materials tag, and so have to rely on a Tag by Category, which limits me to the material name.  I want to be able to refer to any of the properties in the material identity tag.
 
2. In a section or plan view, I can use a material tag, so I can refer to Description, Comments Keywords, etc, but the tags keep going blank and need to be "reloaded" anytime I change anything in the view.  If I change the crop boundary, change from Show Parts to Show Original and return to Show Parts, change scale, anything; the tags return to ?.  I have to select each  tag and then click off of them for the parameters to be displayed; I feel like I am back in ADT with refresh and reload all.
