Nokia N80 help!!!!

I just purchased a Nokia N80 today and I can not find in the manual where I could set the call answer mode. I want to be able to have it in the ring&vibrate mode because I work in a noisy environment. I then want to set the phone to silent at certain times. I also find that when I go to the contact screen to search for my contacts I have to go to options and select sim card contacts. Is there any way I can just select contacts and have it default to my sim card contacts. Thank you for all your help in advance.
