Which of the following is correct?
1) I kicked Tim the bag
2) I kicked Tim, the bag (with a comma)
I want to say that I kicked the bag to Tim, do I need to put a comma after Tim?
The first example is correct but perhaps a little difficult to understand. Generally when a verb has two objects you will write it as a prepositional phrase with the words "to" or "for". For example, "I kicked the bag to Tim". However when one of the objects is a pronoun, you can put both objects next to each other, for example "I kicked him the bag". This page has more examples. The second sentence looks to me as if you kicked both Tim and the bag.
