Bit late now, I guess; but you probably should have had it tested for
compression leak into the water jacket.  There is a simple test that any
radiator shop can do; but the car has to be running to do it.

Yes, definitely, open or remove the block drain and flush out as much crud
as you can.  It's not uncommon to find it blocked, so you may have to dig it
out through the hole.  This is normal periodic maintenance, not just for
when you have cooling problems.  The hole doesn't go in very far, though, so
you'll have to turn the corner if you don't strike water first.

I'm not sure I understand.  The heater valve should block most of the flow
(although it might weep a little) through the valve; but the return line on
the other side is now open and there is nothing blocking it.  You'll get a
lot of water out there.

Taking the old one off should be easy, just turn the lock tabs, remove the 4
bolts, and pull the whole mess off.  There is a detailed procedure in the
workshop manual, but that's basically it.  Since you won't be reinstalling
the fan, you can skip the part about noting balance weight position.
