How do I get a skeleton's spine to be becompletely straight along the X axis?

Hey! I'm trying to align a skeleton with a character model in Maya. I made a video to explain what I'm trying to achieve:

 

 

I've posted about this here before, but the solution I found doesn't hold up. Setting the joints' X translation values to 0 doesn't solve my issue, and some joints have their pivots rotated to where their X axis doesn't correspond with the world's X axis.

 

For example, here's a joint that's off-center:

All of its values are set to 0, save for its X translation.

 When changing the joint's X translation value to 0, it moves up and right:

What's the simplest way to get a skeleton's "spine" to be completely straight along the X axis? I've attached the project file to this post!

I think I found a solution! I made a video demonstrating it:

 

 

In short:

  1. Open Orient Joint's options panel
  2. Check "Orient Joint to World"
  3. Click "Orient"
  4. Adjust the joint's X transformation under "Move Settings" in the Modeling Toolkit (Make sure it's set to "World")

you can just select all the joints 

 one way to do that is select the root joint, and Select --> Hierarchy

using either the options box, or hold shift + w to get the move tool options  marking menu. 

set the space to "world" 

 then in the status bar  change the input to "absolute"  and type 0 in the X field

 

I am curious how you even ended up with such a crazy looking spine. and or didn't just re draw it from the side view ( which automatically places the joints along X)  

or in the front view. just placed the joints, and holding "shift" automatically created the joints in a straight line.
