If you're rooted, Gemini app manager is a good way to keep the amazon appstore in check. It can turn off the appstore's autorun ability so it won't run unless you want it to.

Dude, that Gemini app manager is more annoying then the amazon apps, constantly popping up in the status bar trying to get me to "use" it aka load their add image for a hit.
