Even though you are all set, I'd just like to chime in with my two cents.

For extreme edge restoration i.e. taking out severe chipping I got myself a coarse cheapo combination stone of undetermined grit from a local hardware store for about $6. It's not pretty, but neither are the blades I use it on and it does the job.

+1 on the one time lapping of coticules, just to make sure they're flat. To effectively dish them out you'd have to hone an insane amount of razors daily, I reckon, even when using a slurry stone.
