The arc of fire for a hull mounted weapon is 45d. When you lay the flame template, does the template have to touch (or be as close as possible to) the specific spot on the hull? And can the template leave the 45d arc, or be positioned at an angle outside the arc?

You place the template touching the muzzle of the weapon, as with measuring any vehicle mounted weapon's firing distance.

You can put the template at any angle you want following the normal template rules (that is, you must cover the maximum number of enemy models possible, without touching a friendly model other than the one firing the template weapon)

The Flamer can still only draw LOS to the models within the 45 degree arc, so assuming there are no other weapons on the tank, it will only be able to wound those models within the 45 degree arc, even if it used different models to inflict it's hits.

Weird question here, but can the flamer template lay over the top of your own tank? Purely theoretical, but imagine a rhino with flamer sponsons. Could it lay over the top of the tank to hit something the actual weapon cannot draw LOS to, but can turn to face anyway?

Yes. IIRC

Yes, it can touch the model firing it as much as you want, it simply cannot touch other friendly models.
