"Enfin, les amateurs d'histoire apprécieront le Vieux Bordeaux"

I thought enfin was used when an expected result occurs (foreseeable outcome) and finalement was used for an unexpected result (unforeseeable outcome).  Is there a better way to keep these two words straight? In the above sentence, how would a visitor to Bordeaux know what to expect before actually seeing the city?

1. The phrase "since then" is translated as "depuis lors" or "depuis" or "depuis cette époque" but shouldn't my answer of "depuis ce moment-là" also be accepted?

2. The verb "has been collecting" is used and is translated as "collectionne" but without knowing how the sentence is going to end aren't we also wondering whether to use  some other verb, as an alternative to "collectionne"?
