How to create a polygon grid using 'irregular' underlying points?

Hello.  I have study plots on the ground, each made up of an alpha-numeric grid.  Since it is impossible to physically lay out a perfect grid in the field, the stakes are not perfectly aligned, and I am using actual grid-stake coordinates in GIS (ArcMap 9.3, but I may have access to 10 if needed).  I want to create a polygon grid over these stake (point) coordinates in GIS, where lines intersect on the actual points.  This is the first step...from here I need to divide each resulting grid square into quarters.  I am a graduate student and something of a novice with Arc, but have tried to teach myself a fair bit over the past year.  A novice-level answer would be much appreciated.  Thanks!
