I have a slope raster and slope polygons generated from the raster. How do you segment on thresholds such as 0-5% slope, 5-10% slope, etc.?

a number of options

An overview of the Raster Reclass toolset—Help | ArcGIS Desktop 

perhaps just Reclassify... or Slice if you want

If would just be easier to remake the polygons from the raster... otherwise you have to reclass the slope field in the polygon as well

It looks like reclassify will work! Thanks for your help!

After reclassify, what operator can be used to remove one of the classes?

Set Null—Help | ArcGIS Desktop 

will set the class you don't want to nodata and keep the rest
