The disc brake kit # K2HR712D that you referenced should work well for you. You would need a quantity of 2 of these for each of your axles. These have the same bolt pattern as your current setup and are rated a 7k. You can verify that these will fit your spindle by removing a current hub and checking the numbers on the bearings. If they are 25580 for the inner and 14125A for the outer this kit would fit the spindle and work well.

This kit will fit a spindle that has a diameter of 1.25 for the inner bearing (like what you said you have), and 1.74 for the outer bearing. You can measure to confirm that as well.

For new lug nuts you would need the part # CE11051.

For a brake line kit you would need the part # DM5425, and then for an actuator the HydraStar part # HBA16 would be the best option.

I also attached a help article on adding disc brakes to a trailer for you to check out as well.
