http://www.coticole.be/wedges.hmtl is a great reference for honing in general. There is a pdf document you can download on how to calculate bevel angle. I would not get hung up on how many layers of tape you use on a near wedge. I probably restore 2 or 3 Sheffield near wedges a week. Most are in pretty bad shape to start. Almost all start with 3 layers of tape to see where things are and end with 2 layers. Using the bevel calculator you'll see the bevel angle is still in the 16 or 17 degrees range even with 2 layers.
The bevel I can see in your photos looks like an uneven grind. That little wedge is plenty stiff and I doubt you can force the bevel to look like that. The blade will not flex like a hollow grind. The unevenness is just cosmetic.
If you have breadknifed the blade bringing it back on a 1K can be a ton of work. I use a 325DMT like Glen uses in his video. His video series on breadknifing is great. Watch it multiple times. There is just too much there to absorb in one viewing. The DMT is very aggressive and can create a crumbly edge with too much pressure but it will get the bevels to meet much quicker. Don't be afraid to put up the blade up and come back to it later.
Good luck,
