The parallels between Beorn and the beserkers is obvious, but the Norsemen portray them as barbaric and savage killers, which Beorn is obviously not.

I'm at work currently, so I am going off my fading memory, but I believe Hugin and Munin were ravens and not crows. Ravens are reverenced by Dwarves in the Hobbit, whereas crows are not (also, 'stormcrow' and 'crows and gibbets' being obvious epithets).

Berserkers being savage and barbaric would depend on one's point of view. Perhaps the Franks or Anglo-Saxons believed they were, but among the various denominations of Norsemen they were considered great warriors and heroes.

See above. Ravens were Odin's special agents.
