H260 Asymmetrical spinnaker

That is essentially the set-up we use on our IP31. Works like a charm.
The one difference is that I do not have a tack line going back to the cockpit but I simply tie the tack line off to the stem head fitting on the bow.

Yes, that's how I do it. Works fine.
Think I'd prefer the tack line be forward of the headstay, so it doesn't saw at the foresail when trimming.
You'll also need a swiveling block mounted a little above the forestay for the spinnaker halyard.

The job of these systems, either the sprit or tacker (what the first thing is called) is primarily to keep the tack of the asym clear of the bow and bow pulpit on a boat that was not designed for an asym.
The sprit has to be very highly engineered ($) to take the load the the asym while reaching. I have seen VERY few homebrew solutions that I consider safe. You can do inside or outside gibes. And you can fly bigger asyms if that interests you, and at a slighly deeper angle. Now the hardware is heavy and often in the way of other things. But done well (and that picture is NOT) it is a good solution.
The tacker is a simple low cost option. Its downside is that it limits how tight you can pull your luff (or use a smaller sail), and you can only outside gibe. You have to figure out the mechanics of the tack line, but other than that its OK.
All of this is better than your asym pulling the bow pulpit off your boat.

For the tack? I think it should be forward of the headstay, the approximate distance (or slightly further) that your parrell beads or tacker allow for the tack of the sail during deployment.

I use the ATN tacker and it works great! The swivel block for the downhaul is located just aft of the furled headsail on the foredeck. The swivel block for the spinnaker halyard is on the mast just above where the jib halyard is.
Get the tacker and fly the spin! I also use the ATN spin sock. I single hand and put mine up and down all the time. I absolutely echo what was already said.....don't use a cheap alternative. The side loading is tremendous. Also, don' t place the spin halyard too far above the jib halyard because that part of the mast is "unstayed" and may be susceptible to bending or breaking.

Although in the last vid the captain is ugly as hell, you can clearly see the tacker in action. Good luck!

I will be back on the boat in two weeks. I have the information on board. I will send it then. I can tell you it is a standard off the shelf asym.
If you have the time, watch this video. I had the spin up the whole time.

That is a question dependent on your intended use, sailing abilities and intended environment.
I had my A2 foot fully 6' longer than a recommended cut, knowing full well that it would be in a top down furler, and would be used primarily in less than 10kts. Outside of this range, that much sail would easily overpower the boat, but since there's much calm here in the summer (at least before global warming did that in) it was a good balance of the three questions.
You can't go wrong with whatever the manufacturers suggest, if you don't have a specific request.
