Tooth fairy的方法确实好，这样一对比，读得好的和不好的都清清楚楚。

è 271: Set up, Verb + Preposition, Preposition doesn’t get stressed.  Please refer to Opencourseware 2, starting at 2:07.  The interesting thing is “She turned on a red light” has different meaning than “She turned on a red light.” (turn on a light bulb vs. make a turn at the red light)”  In 271, the stress is on the last non-function word “camp”.

è 277: flashlight, stress should be on flash, not both.

è 282: Starting a fire without matches, tone over raised on "matches", sounded like a question not a statement.

I think you've marked all the differences.  Other than that please pay attention to some pronunciations, for example  nineteen, camping, flashlight, is that.
