Setting ignition timing

I went through a search and I could only find the basics..So i need to know Which plug is #1, which vacumm line is #2, and if i should set it to TDC or x degrees off.

And anything else I should know to be able to do this.

Here's a start looking at the motor #1cyl is too the far right. Vaccum advance line 2 is the inside port on the unit itself. It should be marked as should all the vaccum lines unless someone change them out due too cracks.
