Help with getting elevation data from LiDAR data?

I was wondering if someone would be able to provide some assistance.  I am reasonably familiar with ArcGIS but have never worked with a LiDAR dataset before.  I have recently been sent one and would like to use the elevation data but I am struggling to know what to do with the files.  They are raster files, and in ArcCatalog the preview shows images with only 1 or 2 colours.  The attribute table only has three rows with values 0, 1, and 2, and a large integer in the un-titled column next to these.  When I plot the data in ArcScene and get base heights from the raster I see topography, but when I go to identify a point I don't get anything that looks like an elevation reading.  For this data to be useful I need to know what elevations I'm dealing with.  Does anyone know how I would find this information?
