'Nother vote for Victorinox knives. If you aren't going to spend $150-200+ for a knife, buy a Victorinox. There is nothing that competes in that price range of the $20 they cost. Also get a honing steel.
All Whole Foods have Creme Fraiche. Most larger normal grocery stores do, as well.
Re: Pots/Pans. I have some All-Clad pieces and they are nice, but I also have Modernist Cuisine. Turns out, the incredibly expensive pans? Not worth it. They cooked a bunch of things under thermal imaging cameras and the single greatest factor was burner size relative to pan size. That's it. The cheap-ass completely stainless steel pan heated up and cooled down at a rate not dramatically different from the $300 All-Clad Copper Core line. If you have small burners the best solution they came up with was to go to a metal shop and ask them to cut you an inch thick 1' by 1' block of aluminum, put it on your burner, put cheap ass pan on top. Also shiny pans cook more efficiently, dark pans end up radiating a lot of waste heat into the room.
I understand Viking and a couple of other manufactures are taking this data to heart and actually making variable burner size stoves, where you can adjust the size of the burners based on your pan.
