Llama is great for setting up automatic tasks based on location/ actions.
ex. turn on wifi when I get home, or open pandora radio when connected to my car bluetooth, etc.
Quickpic is a good gallery app, better than stock IMO
Quickoffice
Package Buddy for tracking packages
Beautiful Widgets
VLC
AVG Image Shrinker for sending multiple photos in one message (otherwise it will give you a size error)
Zedge for ringtones and alert tones
