Hello, Casey. I'm glad you're finding the thread useful.
You don't need to remove/change all the dialog tags to "she/he said," but you do need to think about all of them. They're spices. Without them, the stew is bland. With too many, its inedible.
I can certainly do another ending analysis after the holidays.
And, yes, it's time for another Christmas Challenge.
This year's Christmas Challenge is A Story in Four Days.
First, decide on what your protagonist's problem is. Then decide on a period of four in which the protagonist can reasonably expect to solve it. Thus, if his/her problem is a broken shoelace, a reasonable time to solve it is four minutes. If the problem is a broken marriage, though, the time scale will be more likely four years.
Now, over a four day stretch, write a short story. On the first day, write about the protagonist's attempt to solve that problem in the first time increment. End with discovering that the problem isn't what it seemed at first; there's a new, bigger, hairier problem. Fifteen-hundred words is a good aiming point.
The next writing day, write about the second time increment, as your protagonist attempts to solve this second bigger, hairier problem. This ends, not with the solution to the problem, but with the discovery that the real problem is something entirely different, and far worse, than the protagonist thought. Again, fifteen-hundred words would be nice.
The third writing day, you'll again do fifteen-hundred words, about the third time increment, as your protagonist tries to solve this new, nearly-overwhelming problem. At the end of this section, the protagonist discovers that the problem is really another thing, and its really, really bad. Horrible. Worse than anything that had come before.
The last day, your writing will: Fill the fourth time increment. Resolve this new, horrible problem (through the protagonist's own efforts). And solve the original problem. Thus (with the shoelace example), at the end of the 6,000 words, the protagonist has the murderer who was hiding in the closet neatly tied up and awaiting the police, and is wearing a pair of slip-on shoes so the shoelace problem is solved (she/he can buy a new pair of shoelaces on the way home from work).
Again, write and polish. Present it to your family and friends on Christmas Eve (while waiting for Santa Claus to bring you a new plot point (you've been good!)), revise it according to their comments/what you thought of while reading it aloud, and send it out (to a paying market!) on the second of January, 2012.
