You are correct in this case because the "and" is separating two words.basketcase said:I believe that the comma only gets used with "and" if you are talking about a series. An example would be "I hate grammar, spelling, and punctuation." The statement "I hate grammar and punctuation" needs no comma (then again, I could be wrong. I studied Engineering, not English)
A comma is also not required when "and" separates two phrases, for example:
I will clean my room and do my homework.
However, when the "and" separates two clauses (a clause can stand alone as a sentance), there is a comma, for example:
I will clean my room, and I will do my homework.
Your example of using the comma before the "and" in a list is correct, but the comma is optional. I like using the comma in the list.
