I was wondering if there is any way to get the result raster from an IDW into either a shapefile or feature class?
Do you want Polygon Feature Class as the final output?
Then, Reclassify the resulting Raster of IDW as desired, and then Convert Raster to Polygon.
The first question should be, 'why' do you want to convert a raster to a vector. Reclassification is going to produce a loss/simplification of data and although the option exists to convert a raster to points, conversion of format is normally a last resort
