I have to say, that I started way too late in the day in order to do this correctly. The Creamy Lobster Broth needs to reduce twice, which left the gf and I very hungry (remedied by a quick gnocchi appetizer!). As it started late into the night, I became impatient and the Broth ended up being more watery than I had expected. Even with the wrong consistency, the broth was very strong and very rich. Its sort of scary how rich and thick its supposed to be. I can see why the portions need to be small, as opposed to my large portions.
I tried Keller's method of cooking lobster, which would have been great if I didn't overcook it in the Beurre Monté. But on the upside, now I have a quite a bit of clarified lobster butter.
I also failed on the parmesan crisp. Burning 2 patches before giving up.
The only hints I can give anyone is to give yourself plenty of time and do as Keller says and strain & skim all the time.
