cfgmaker finds them properly for me.  I also wrote a template to graph
the transmit and receive power levels.  That's a little trickier to do,
though, since with negative numbers you have to manually tune the
rrdfile (rateup can't handle negative numbers).  If you are using
rrdtool as a backend and are comfortable running rrdtool tune, I'll
gladly share the template...

Shouldn't care.

Yes, you will want to use the 64 bit counters, which are accessible
using either snmp v2c or v3.
