Always a good idea.

NO! No penetrating oil is needed!

The bottom bolt has a 3/8" square hole in it. You need to use a pick to
remove as much or the dirt from that hole as you can so the ratchet's
3/8" square drive will engage fully. If it slips and rounds off, you wil
be AWFULLY sorry!

The upper (fill) bolt is a regular 19mm socket.

Tightening torque for the lower bolt is 29 ft/lbs. The upper bolt is 33
ft/lbs.

For the cheap price (about a buck apiece), get the proper washers from
the dealer. The drain washer is the same as the oil pan bolt washer. The
fill washer is a lot bigger and has its own part number. I just did mine
and can't remember the part number, but the dealer will be very familiar
with it.

Pretty much.

Space is definitely short. Draining is easy. Filling is not. The fill
method suggested is OK, but you need to make 100% certain of two things:
1) that NO dirt EVER drops into the funnel, and,
2) that the funnel is well ABOVE the fill hole. The higher the better.

A third point is that the car should be prefectly LEVEL front-to-back
and left-to-right. You can use a carpenter's level to ensure this.

You'll spill a bit as the oil drains out of the fill hole once the
proper level has been reached, so have an oil-change pan under it.

Also, if the fill hose isn't quite all the way into the fill hole, oil
can dribble out early, leading you to erroneously think that you've
filled the tranny properly.

No no no no no to all of that.

Viscosity and mineral/synthetic has nothing to do with it.

Honda DID used to recommend ordinary 10W-30 motor oil, but motor oil has
changed dramatically since then. The advent of OBD-II around 1995
resulted in a severe reduction in various traditional motor oil
anti-wear additives. The reductions were done in order to allow
catalytic converters to meet new government longevity regulations. The
reductions also, unfortunately, meant that ordinary motor oil no longer
possessed the proper qualities for manual transmission usage. That's why
Honda developed their own MTF. MTF contains exactly what Honda wants to
see (better than even the older motor oil, actually).

Honda knows the chemical composition of the metals and plastics used in
their bearings, synchros and gears. Honda MTF has very specific
additives particularly meant for Honda's own quirky designs. Genuine
Honda MTF is the ONLY proper stuff to use in Honda manual transmissions.
