1) The majority of my time is at a work station with a computer. I am not at the computer when I am filing, making copies or getting the mail and that's about it.

2) I use the internet all day for work. The student records are all online based and so I have at least 3 tabs open, usually 5 all day when I am at work. When at work I'd say it's 80% work and 20% personal as I usually have a tab open with my gmail and/or some other no-brainer site for when I need a break from dealing with the students and/or whiney professors.

3) Gmail Chat, all day on my BlackBerry and then usually most of the day on my workstation computer in its own tab.

4) Not official ones. I often receive FB messages from my boss or my boss' boss instead of official email when they want me to run to their offices. Weird and I find it slightly unprofessional but they are the ones calling the shots so if they want to ping me that way I'm okay with it.
