Converting LiDAR data to Contours

At present, I have ArcGIS 9.3.1 and have purchased several tiles of LiDAR data (XYZ format and LAS format) for my entire county.

Can anybody provide any guidance or direct me to a procedure somewhere that outlines how to convert this data into smooth, seamless contour data?  Can this be accomplished in ArcGIS 9.3.1?  Is there additional software that will handle this task better?

Thus far, I have found procedures that show how to convert these tiles by using the LAS to MultiPoint utility, and then creating surfaces/contours using Spatial and 3d analyst.  However, the contours do not match up at tile boundaries. 

Any thoughts, recommendations, or advice are appreciated.
