I'm not sure what the question is? The needle and seat are not generally something anybody ever messes with, other than to replace during a rebuild, or to set the float height. I'm not aware of any various sizes, and can't think of why there would be. There aren't any "sizes" listed on CBs parts list.
The CB jetting chart is a great place to start. With a 1915, I think 55s are going to be pretty close. The 130s may be a bit fat, but you won't know without an AF meter (unless you go WOT, pull off the road, and read a plug).
I wouldn't get carried away with the correction jet.
