task manager, alarm manager and more for n91 symbian s60 3rd

hello.. i'm having a n91 with s60 3rd edition and it's really quite hard to find programms running on thi smobile phone..

2 programms i'm looking for are quite important....

1. i'm looking for the alarm manager.. i found it here but it isn't working... can anyone help??

2. i'm looking for an task explorer or sth. like this to see which programms/tasks are running

3. which icq-client is best and allows connection via wlan??

4. where can i get more themes for n91? found the one in board but want more.. :-)

5. are there any other must-have-programs??

6. does someone know a video player, best would be for divx-files, which is running on s60 3rd?? maybe there is a java-based one?

thanks a lot for your help...
