Is there anyway to get mounting instructions? How far from edge, etc?

I too was looking for this info. I was doing a new insulation and have never done this before. You need a 35mm hole drilled 1/2 inch deep. The center of the hole to the edge of the work piece edge is 21mm or from the edge of the hole to the edge of the door is 2mm. If you have to do more than a couple of these you should look at getting one of these. Kreg Tool Company KHI-HINGE Concealed Hinge Jig I used one and set the offset to 3mm

Is there a way to restrict how much it opens to 90 degrees instead? To prevent it from hitting the wall or panel next to it?

No, it opens up to a 90 degree angle. It doesn't open any wider.

Would these work for a lid on a storage bench? If so, what would be the weight limit per hinge?

They will work, but they will not hold open the lid, these will just hinge the lid. To hold up the lid, I recommend a search for “Gas Strut lid support” and use both products in conjunction (I did this with some horizontal cabinets in my house.)
