Depends on your goals.

If you're looking to put on muscle, YES....try to get carbs within an hour and protein within 2-3 hours (after workout).

There's mixed opinions on all this...I read recently that protein BEFORE workouts is more benficial...who knows (?) Anyway...I'd go with a carb snack IMMEDIATELY AFTER your workout, and then a protein/fat meal a few hours later.

Best of Luck!
