Your preflight briefing will depend on what type of flight you are planning - a training flight briefing will be quite different than an airline brief. But there are some factors that will be common to all flights:
Mission Objective
Weather
NOTAMS
Aircraft Performance
Aircraft Maintenance Status
Route of Flight
Fuel
Takeoff Briefing (PF)
Departure/Arrival Airports
Rejected Takeoff
Automation
Crew Member Duties/Expectations
Arrival/Approach/Missed Approach
Risks
Training Objective/Elements
