Would someone please help me with modding? Preferrably explain coding and all that to me, not the basics, but mroe specifically on making a block, setting it in, and giving it properties. I've got basics finished, and the right programs for it to be done with.

In this mod, I need help with changing properties of the key components of redstone.

Redstone torch
lever
pressure plates
buttons
redstone repeaters (maybe)

I'm also adding in something new. You can check out what I want done, and could use help with, by reading what I have posted here.
