I use multiple context for my shopping errands. I have one for grocery market, hardware store, miscellanous, etc. I add items to my shopping list as times come to mind and when I'm there it's easy to check that I have everything I need. You can also select the top most shopping context and all of your shopping items will be shown in a list with headings.
Try having multiple context for your University and see how it works for you.

I would not put scheduled meetings in Omnifocus, I'd put it in a calendar program with reminder messages. I would put in all tasks that are required to get the meeting scheduled.

Omnifocus is quite a powerful program and will take time to really put it in your daily flow of work.
