I'll take the easy one. It looks like you have a Record crank ("C-Record"). The 4 chainring bolts were the Record trademark once they left Super/Nuovo Record behind.
As for the other stuff, the monoplanar brakes are nice. The rear derailleur has steel pivot bolts. Makes me think the group is an Athena group, with an upgraded crankset.
The Ergo levers were the same for a while - they only made one set. Since it's Ergo, it's 1992 or later, at least for the levers. I don't think the components are from 1987, they seem too new. Back then it was Victory/Triomphe and NR/SR.
If the frame has 10-Speed Drive on it, someone can date the frame. 10 Spd Drive imported frames and painted them state-side, a vast improvement over the "we paint'em you chip'em" Italian paint jobs of the era. I don't recall their years but I'm sure someone here does.
Take a pic of the drivetrain (cassette, rear hub, front hub). That helps ID the different groups.

Regardless it looks like a nice bike.
hope this helps,
