If you can grab a copy of the 2014 Charlton Vol 1 and check page XX in the intro it will give you the specifics on the different finishes
PLs were struck up to and including 1967. After that they went to BU (NBU on ICCS certificates) because of the change from softer silver to harder nickel coins. Although it took some time for the change in nomenclature to catch on so you'll sometimes see coins from the late 60's and 70's graded as PL. 2010 was the last year of issue for BU sets and since then the sets just contain Circulation coins (MS). Proof coins were first struck in 1981 I believe with the Trans-Canada Railway Centennial silver dollar.
UNC is widely used across both PL/BU/MS coins so generally best to ignore it. Technically it refers to Uncirculated Circulation strikes though.
BU coins are issued in BU sets. All sets from 1968-2003 inclusive are BU but from 2004-2010 some are UNC (circulation strikes) and some are BU. Best to rely on a catalogue to figure out which are which.
The main difference between BU and Circulation is that for BU "Coins are struck by a slow moving press using high pressure and polished dies. Blanks are inserted, and coins removed by hand."
