Is it worthwhile fairing the "curviness" of the flare before the glass goes on?

I'm thinking by doing it that way, it will provide a tougher hull to have less fairing compound "outside" the glass.

You don't want any fairing compound underneath the glass, it would weaken the assembly. You could build up with epoxy and structural fillers, but that's going to be hard to sand.

Yes, no fairing, your next step would be to precoat the wood with a thin layer of epoxy so that it does not draw all of the epoxy from the fiberglass when you lay it down. Just go with what you have and then fair afterwards, for the easiest way to go.

I've got a question regarding the taping of the seams.

The plans I have say:
- Build the outside seams.
For this boat, we will build several longitudinal seams: keel, two seams at the chine step,
one long seam between the upper and lower topside and seams over the slits.
Do not aim for a complete lamination schedule right away. Build a single tape seam along
each seam including the bow and around transom, then check the hull and bottom for
fairness.
Is this saying there are two seams to tape at the chine, or the chine should have two layers of tape?

I found in another thread a builder who seems to have used 3 at the chine and keel?

I've just found my answer.

Is there any reason I couldn't do the following?

I had always planned to do an extra layer on the outer hull anyway. We have a lot of reef around my area and the extra layer would give me that little extra piece of mind :)

You don't ever tape on top of each tape; they are staggered.

Lay longest first in this scenario. If you have enough glass a 1" stagger is best.

Sure. The drawing was a rough approximation. I would ensure staggered joints as I progressed up through the layers.

How would you fair that hump?

Wouldn't the hump be greater with only 2 layers and the extra seams?

Do you mean option A over option B?

I've seen advocates for both and never really established an answer for which is best. My past glassing I've always done B.
