Watershed Delineation Using LiDAR insted of DEM

Hello Everyone, I'm new to ArcHydro and delineation. However, I've been assigned a project in which I need to take LiDAR data (I also have access to DEM and aerial photography) and I need to auto-delineate watershes.

I have just installed ArcHydro sucessfully (I'm using ArcGIS 10 in Windows 7) but I do not know where to start. Has anyone got any tips for delineation using LiDAR data? I can use the DEM and aerial if I need to, but I'm supposed to mainly use the LiDAR (of which I've never worked with before either!)

I've found some helpful tutorials using DEM, but can this be done using LiDAR?

Thanks so much for any guidance you can suggest.
