When I get a missed call or a new text message, when I wake the phone up there is a translucent banner that says "x # of missed calls" or "x # of messages"

I installed an app called Voicemail Alert. It puts a little red flag in the notification bar on top when I have a new voice mail.
I'd rather have the banner (more obvious), but I can't figure out if that's even possible.
