I tried the whole just ignore them thing, even turned off auto update so they wouldn't, then got tired of constantly skipping past them to update the things I did want. Finally I caved and just let them update. Then I rooted, and now updated or not they just sit there frozen. As for apps that aren't bloat if you don't use it uninstall it, then use a file manager and delete the folders they leave behind. But do it when you uninstall, or like I did before I started doing that, sit looking at all that memory wasted because you can't remember what's installed and what's not.
