Regarding your k-nearest neighbor question, you would have
to edit your k-nearest neighbor matrix to make it symmetric.
Manually editing your matrix can be extremely time-consuming
(especially if you have more than 100 observations) and it
is easy to make errors in the process.
About your 2nd question: The easiest way to create maps
using multiple layers is to choose the "save results" option
in GeoDa (right-click on map), which will add fields to your
table (e.g., for smoothed or LISA maps). You can export
these fields as part of a new shapefile and open them in a
regular GIS. Then you can map the GeoDa-generated fields in
addition to other layers.
