PO installed a points-type dizzy. I would like to do a TFI upgrade and was wondering if this is compatible with points? Or do I need to replace the distributor with electronic-type?
Forgive my ignorance, don't flame me too bad! ;)

I think that you'll need to upgrade to the electronic dizzy. AFAIK the dizzy cap for points is different from the one on the electronic dizzy. So the TFI cap wouldn't fit on the points dizzy. And who knows what else wouldn't work ;)

Below is a quote from the /tech library/ on this site regarding the dizzy for a tfi install.

FOR OLDER VEHICLES:
*1977 And Older 304 & 360 CID V-8 Engines With The Delco Breaker Points Style Distributor. You have three choices,
1. Up Grade to the Motorcraft distributor & DuraSpark ignition module, and add the upgrades described above for the Motorcraft distributor.
2. Use an electronic ignition conversion kit for the Delco distributor. If you install an electronic trigger in the Delco distributor, you may use the DuraSpark or MSD ignition modules, but you will have to go to the aftermarket for adequate distributor caps & rotors.
3. Use a MSD ignition module that will work with breaker points. You will still have to go the aftermarket for adequate distributor caps & rotors.

*1977 And Older 304 & 360 CID V-8 Engines With The Prestolite Electronic Ignition. The Prestolite Distributor can easily be recognized by the large vacuum advance canister just below the distributor head. AND THE DEAD GIVE AWAY IS THE VACUUM ADVANCE IS MADE OF PLASTIC. The only choice you have is to upgrade to the Motorcraft Distributor and DuraSpark or MSD Module.

If you don't have all the wiring and motorcrap box already instead of swapping the dizzy and putting all that in I would just get an HEI dizzy. It may cost a bit more than the regular TFI upgrade but there's only one wire to hook up. MUCH simpler. Here's a link, you'll have to email Zack for a price and such:
