Here is a good reference for cams:

I'm not entirely sure follow, but:
There is supposed to be a pin that you line the notches in the crank pulley up with the second notch from the left. Its at about 1:00 on the block. If nothing else you should be able to tell where it was supposed to be if its broken/missing. You gotta know its exactly on TDC.
Unless i'm forgetting something you don't have to do any real fiddling with the lower chain, just get it on there and get the upper gear in its place. Get the upper chain lined up right while you're doing that and you should be good.
For lining up the upper chain follow the jim wolfe guide.
As for the distributor itself:
Look at where the number one spark plug goes in the cap. You line up the rotor button with that spot exactly. I think its right above the connector that goes to the ECU, but there is actually a little V notch in the distributor that is almost exactly in line with #1. Makes it easy to get it right without putting the cap on it for reference.
Just rotate the button a bit counter-clockwise from where it needs to end up and push it in. If its off, work from there until you get it.
Sorry, not the best description. There is a great thread somewhere on the web with rebuild pix/info but I can't seem to find it.
Find yourself a buddy at GED who will help ya out.
