He retains Beorn's interest by introducing a few dwarves at a time, while he is telling his story.
Bolg was killed by Beorn who was in his form as a great bear. Beorn scattered the bodyguard and pulled Bolg down and crushed him!
He verified that the story that Gandalf and the others told him was true. He captured a goblin and a warg and killed them.
Lots of individuals gave Bilbo advice, Gandalf is most prevalent. Beorn as well. He is given small bits from others.
Gandalf proves to be a very good manipulator when talking to Beorn because of how he brings the Dwarves in at very high points in the story. He does this so Beorn would stay interested in the story. I hope this answered your question:)

Bilbo Baggins, Gandalf, Thorin Oakenshield, Gollum ,Smaug, Bard, Beorn, Thranduil, Elrond, Fili, and Kili.
Both Beorn and Gandalf warned them to stay on the path.
They enter in pairs because Gandalf tells them to do it. They don't want to go in all at once, so Beorn will think they were trying to kill him The dwarves must enter Beorn's house in pairs so that, as Gandalf tells their tale to Beorn, each entrance does not seem very imposing and Beorn's interest in the story is built up. Then the group will be able to stay with Beorn.
Lots of individuals gave Bilbo advice, Gandalf is most prevalent. Beorn as well. He is given small bits from others.
Beorn is a skin changer in The Hobbit.
{| |- | Beorn was off checking up on the story that Gandalf and the dwarves had told him. He returned and told them that he had confirmed the story. Beorn captured a warg and a goblin and after getting information from them he killed them. The warg's skin and the goblin's were mounted on the wall. |}
We know Bilbo, the hobbit, was well guided and well guarded on his way home because Gandalf, the wizard, accompanied Bilbo all the way home to his hobbit-hole, while Beorn, the shape-shifter, accompanied him just until they approached his house in Mirkwood. Also because Beorn gives very good advice about Mirkwood.
