Use the -l option to ls and compare to the date you installed your kernel.

It doesn't like you're using them, though.

It's hard to back out an installworld if your new kernel is broken.

Might be worthwhile :-)

Again, it's well described in the handbook.

Doesn't seem to have fixed the 'broken mptable' message.  This may
indicate broken (non-spec-compliant) hardware.

Yep..one step at a time.

Looks OK as far as stepping goes, I'm not an expert on SMP hardware to
interpret any problems with the rest.
