Re: points firing
Something very important to know: The end of the cam has a SLOT in it that the tang on the distributor slides into. The slot/tang are offset from the centerline only 1/16 of an inch.
The reason it is offset is so that the distributor drive is always mounted in the same way - you can take the distributor on/off and not influence the timing. BUT, it is very easy to have the distributor rotated 180 degrees OFF from where it should be - then you think it is close to fitting (so you force it on) and you try to somehow get the bolts back in their holes. Make sure the orientation is correct - or you'll ruin the distributor and the engine will not run.
You might even succeed in wrenching the bolts in . . . which will crack the distributor housing when you tighten them - or when you turn the engine over.
Lastly, there is a gasket that goes underneath the distributor - you'll need a new one. It is important that you clean the timing cover and back of the distributor well. I'd use a little thin gasket sealer on the gasket (like Gasgacinch - from Edelbrock or Jegs) - but don't clog the vacuum transfer hole. You need the gasket to seal the vacuum port, but not obstruct it.
If you're not familiar with these distributors (which it sounds like), you can learn a bit in this process (if you understand distributors in general). If you want to really get it setup properly, send it to either of the two guys mentioned earlier - they know what they're doing and have the necessary distributor machine to really set it up correctly.
Best of luck!
