In the movie it is clearly the left hand. Specifically the index finger (wearing the ring) on the left hand was bitten off. Frodo wore the ring in that scene on the index finger, not the ring finger as might be expected.

Gollum. The name was given to him by his relatives, due to the "gollum" noise he made in his throat.
Gollum possesses the ring in The Hobbit and Bilbo gets it from him. In the third book, the return of the king, he briefly has it again in mordor at mount doom
It depends if Gollum is included in option. If you want him, before starting the game check "Ring Heroes ALLOWED". Then Gollum will be somewhere on map. He is usually hiding and sneaking around. If you meant Gollum as a Hero, you need special map or mod.
