Re: Tips that I enjoy the most.
For the specific example of the stuttering, it's usually best to go light on the stuttering. If you're going to use more than two repetitions of a letter or sound, I find that it's best to use ellipses instead of dashes, because otherwise it just drags on too long and isn't very appealing at all. Otherwise, you're quite right on these points, though I would clump in past and present tense with the 'first-second-third person' discussion; second person is normally done in present tense to increase the illusion that it actually is the reader acting out the story, and past tense is normally done with third person to make it seem more distanced from present events.
