Fair play.
That BB is as good as it's going to get (Record Pista BB aside).
At least you'll be able to use it in the wet without worrying about the bearings.
You'll need a Campag cassette lockring/BB tool to fit.
The NDS cup (being a a road BB) has no lock ring, so can develop a creak if fitted dry or without enough grease. Ignore the pre-applied locking compound and slather plenty of copper grease on both the shell and BB threads and you'll be fine. Mine both needed a NDS re-torque after about 2 weeks, but haven't needed to touch them since (15 & 3 months respectively).
I don't believe that's a 52t. Appears to be the same chainring as the previous image they sent/you posted. Reckon that's a 49 or 50t.
Photo from this post (https://www.lfgss.com/comments/13176017/) is with a 53t and shows a greater distance from tip of spider to teeth than that... 1t smaller but surely the spider-to-teeth gap should be greater than shown with a 52?
