Default Motec - going from 1 coil to 8

Every now and then I have to admit defeat and admit that my Google search skills aren't what they used to be. For that matter, I'm so clueless about search engines I got excited when Alta Vista was talking up its IPO all those years ago...

Anyway, an EFI question. My 351W currently has an M800 Motec with a crank trigger and an MSD distributor modified to run as a cam sync (7 of the 8 reluctors removed). I then have an MSD Digital 6 running a single MSD coil.

What do I need to buy to convert to coil near plug? Current plan;
Convert magnetic pickup to Hall effect in distributor.
Blank the dist cap as the dist body will now simply be a cam sync and an oil pump drive.
Buy 8 new Delco GM LS coils.
Run M800 in waste spark so I don't need to buy an ignition expander.

So here's where I lose my way. Do I need anything between the M800 and the coils to boost/control spark? If not, can I remove the MSD Digital 6? Is it optional to either run an ignition booster or not? It seems that the coils are running in a squillion cars with 15 to 20lb boost (which for me will be about 900 to 1000ish engine hp and 700 to 800lb/ft if power/torque somehow factors into the equation but I guess boost pressure would be more relevant for the coils).

Am I missing anything else?

Thanks!
