Spritz/ Cookie-Press cookie questions

The posts on the "What Cookies are you making this year?" thread have inspired me to perhaps try spritz cookies. I've got my mother's old Mirro press, still in the original box, which I have never used since she gave it to me (but remember making cookies with her when I was a girl). Fortunately, I have the instruction booklet, which includes a number of recipes. But does anyone have any recipes and/or tips for a novice Spritz cookie maker? Right now I am leaning towards a recipe called "Orange Crips," as I've already made cut-out sugar/butter cookies and am inclined towards a different flavor profile.

Also a really dumb question: Do you put on sprinkles before or after the cookies bake? I've been icing my sugar cookies and its been such eons since I've made cookies with sprinkles I really cannot recall.
