I did that once, but I won't anymore. (comma)
No. There is no rule that a comma must always follow the word "which." In a parenthetical or appositive phrase, however, a comma may be required.Example:I did what I thought was right which, as I came to find out, was not.

Not necessarily. There is no word in English that requires a comma before or after it.

While I would not say that every use of the word anyway requires a comma, without exception, it is true that anyway often does call for a comma. Just remember, if you would pause slightly while speaking that sentence aloud, that is where a comma should go.
There typically is not a comma when using the word or in a sentence:You could have toast or cereal for breakfast.The reason someone gambles is either for excitement or for money.If you want to indicate a pause between the options, you would include a comma before the or:"we could go to the park, or if you'd prefer we could go to the beach."

Before
There is no word in English that necessarily requires a comma. Commas are features of the sentence. Sometimes a comma may go before if, for example when it introduces a new clause: We will wear rain-gear, if it becomes necessary. And sometimes a comma may go after if, for example in this sentence, when another thought is inserted into the structure. Generally there is no comma with if.
