it means that apt wants to update it, but can not due to a depends/conflicts or missing package issue. Yes, you can remove any task- package after using it. However if you do so you do not get new packages as the task changes and matures. to find out the cause of your problems, do a 'apt-get install task-helix-gnome', that should tell you why it is being held back.
