You're lucky that you can even get amarok to run in gnome. I've been having issues with dcop which is preventing me from running any kde app properly (and I've installed all of the necessary libs and stuff).
About your "freezing" problem...maybe amarok is waiting for the user to enter credentials to get access to the files on that windows share...to fix that, just make sure you save the username and password when it asks for it for the first time.
