comment Can a new point automatically be populated with data from the containing polygon
@Hairy: Your script updates a polygon layer not points. The geom variable wont be created as you don't have access to X,Y directly. Use geom = row.Shape.getPart() instead. Moreover, the script may not be effective while many polygon as it loops through all polygons for each point.

comment Clipping Vector File based on certain Raster Values using ArcGIS Desktop?
My first thought was also CON tool. But in my created Slope rasters this tool didn't recognise VALUE field. That's why I recommended Reclassify tool. BTW the real problem here is not HOW, but operations on huge vector layers.

Have you seen gis.stackexchange.com/questions/16110/… for some hints on handling big rasters and vectors?

What do you mean '"Clip" crashes'? Does it throw any errors or ArcMap is in No response state?

When converting raster to polygon, select option 'Simplify polygons' - this reduce the number of polygon vertices. Moreover, try to do your analyse in File Geodatabase.

comment Looking for system specifications for a modern GIS workstation
In case of ESRI software, it's better to have higher cpu frequency than additional cores.

comment slope and mosaic datasets
You don't need to update overviews for slope calculations. When you still get wrong values try to create 'traditional' mosaic from your rasters: Data Management Tools -> Raster -> Raster Dataset -> Mosaic

comment slope and mosaic datasets
Try creating new Mosaic Dataset, set Pixel Type 16_BIT_SIGNED (this should cover all elevations). Then again Add Rasters with Calculate Statistics advanced option checked. Check in ArcMap if you have correct elevations.
