Not quite. You need to capitalize the S and remove the period. We don't typically use double punctuation. Frankly, the whole phrasing of that statement would be very bizarre from an American's standpoint. We would typically say something along the lines of "Is the question worth caring about?" It's more concise and doesn't emulate an inner dialog. More to your larger point, the placement of punctuation within quotes, while grammatically correct, has the feel of leaving a sentence incomplete.
