I haven't heard of anyone using FLAC for 192khz, so you'll
probably just have to experiment. when you have some results,
let me know so I can tune the defaults better.
for high sample rates, tweaking -b and -r (and to a lesser extent
-l) is important
for high resolutions (24bit), -l, -e, -p, -q are relevant.

no, it's a limitation of native FLAC. if the only reason to
use --lax is for 192kHz, the files will still be streamable
but some hardware players may not support a sample rate that
high.

never heard of w64 before now. if it's close to WAVE it's
more likely. is there a spec?
