AZCAT,
I will try and get the pictures you requested but for now I will just describe it.
The attachment point on the main beam is pretty simple. Mine basically consists of a plate or stainless with an inch long pin sticking off it. That is rivited to the main beam directly in front of the mast step. Then the pole has a hole at the end that you simple stick onto the pin. The tension of the bridals holds it on the pin. I had trouble picturing it at first also, but it is really simple once you see it.
As for the snuffer line.
I did not run mine through the tramp, it comes out the end of the bag just in front of the front crossbar. Then it runs up through an eye strap i have mounted on the front beam. Mine is a continuous halyard and dousing line so after what was mentioned above it loops and runs through the halyard cleat and up the mast.
If you have an end pole snuffer you are going to run into the same problem that I did when you douse. All the spinnaker is going to try and bunch up at the end of the pole and you will never get it to douse correctly. To fix this problem after I have lead the dousing line up through the two patchs in the spinnaker I tied a knot in the dousing line between the two patchs. This causes part of the spinnaker to go in before the rest. It made it alot easier and has fixed that problem.
I will work on getting you those pictures.
