comment How to quickly fill multiple gaps in a series of adjacent polygons
I think that may blow away some of the gaps that need to be preserved. It will also round corners.

For this exercise I am using Pleiades 50cm pan 4-band (2 m MS) Imagery, geotiff converted to ESRI FGDB raster.

comment Labels not appearing on any layer in ArcMap?
This is a fairly common problem in ArcMap. You could have also tried running MXDoctor and defrag on the map document which often corrects such problems but not always. Starting over with a new mxd is usually a good second step in troubleshooting these issues.

comment 50cm imagery - aerial or satellite?
@Aaron - both. Initially the aerial. The image was clear and high resolution but prone to long shadows and similar visual deficiencies such as optical illusions (trees look higher that they are). Aerial looks good as a map underlay but we found it lacking in the "analysis" area so we recently ordered a Pleiades 50cm satellite - new collect. IMHO, the satellite image, which does include NIR, is far more suitable for GIS analysis; tree species and stands are clearer to identify, outcrop pops out, wetlands and water features easy to delineate, no long shadows and optical illusions
