Now I need to research prepping them for lapping and re-read the pros and cons of lapping

Only thing you gotta worry about is the eccentric shaft play and possibly adjusting the spacer in the front assembly.
Mazda has the specs for this in the FSM.

On my first assembly I actually just shaved down that spacer. I had to replace the front rotor and housing on my first rebuild. I now have a second spacer from an N/A engine I tore down. If I do have the iron lapped or replace it; hopefully one of those spacers has the correct end play.

For the record shaving down that spacer was a PITA and took forever, but I didn't want to wait a week for shipping to get my engine together. What I did after I saw end play was out of spec was take apart the front stack. Sand down the spacer and constantly was checking with my micrometer to make sure I had it evenly shaved. I believe I checked on either 6 or 8 pts around the spacer. So I'd take some material off, assemble the front stack, check endplay with my dial indicator and repeat the whole process till end play was within spec.
