World to screen.

[Vector]

I'm looking to take an XZY position and convert it to an XY position on screen. My goal is to write a helper system that renders cuboids of blocks for given id's.

 

Also are there any amazing tutorial sites that would answer almost any other question like this.

It looks like updateRenderInfo (ActiveRenderInfo.java) does the opposite of what you want. It should be possible to use the GLU.gluProject as long as you setup the appropriate transform matrices.
