a) I can't help much other than I have run the Open Country and liked them. I ran a 70's series on my old Trooper. I liked them enough that after almost 50k I bought a 2nd set.
b) A 275/60/17 would work/fit just fine. The Speedo will be fine as the overall diameter is about the same as the OE tire. Diameter can affect speedo readings; width does not. I have never seen a 270/xx/xx, only 265's & 275's. A 275/60/17 may be a hair shorter than OE. Worn 265/65 and new 275/60's are probably identical.
c) There'll be no issues.
