I use Unified Stats and Sumbitpimp in parallels.
I have also used an app called Photosite Timesavior, which is simple gallery builder for the mac, before I bought Arylia.
Other apps.
Adium for multi-chat client
Cyberduck opr Fetch for FTP
wget for ripping those pesky FHG for building your own submitted galleries
