The Text Editors menu is all there is, and it doesn’t allow you to do the things you want. When you right-click on an aspx page, click “Formatting and Validation…” and then click the button “Tag Specific Options…” you get a bunch of settings per client- or server-tag, but not for the <%-tags.
As for the second part of your question, Ctrl-E,D formats your document, but does not insert the spacing you want.
