The team workload view shows you your team's workload, how are tasks distributed and if someone has too much or too little work. Click on the calendar to add a new task to someone, it will get automatically assigned to that person. On the left, you'll see all you team users and the right side shows the events. You can switch between month, week and day view
The resource view is in sync with the regular calendar view, it's just a different layout.
All the other functionality is the same as the calendar view. You can move tasks around, assign people, change name and move to different project.
