- Create quiz: “Number of questions” box is ridiculously big

This one anyway is a theme issue. In drupal.css, there is:

.node-form .form-text {
  display: block;
  width: 95%;
}

This overrides the length and maxlength attributes provided through form_textfield(). Can't do much about this one. :\

"- I Wonder if there's a way to include all the question types underneath the quiz module, rather than them having to be enabled separately as things like "multichoice" without any context as to where they belong."

Ran this past Robert awhile back and he said not to worry about it for now.

"- There should be a way from the quiz creation screen to create additional questions, rather than solely selecting from questions that have already been created, as this may be counter-intuitive for a lot of people."

Addressed this by adding links to create each question type from "add questions" tab.

Marking issue as "fixed."
