I would suggest reading the Help files provided with ArcGIS. In the Spatial Analyst toolbox, there are a few toolboxes that will interpolate the points to a surface using various methods. Each tool has help associated with it (just right click and select Help) some are very simple tools and some use some very complex formulas to interpolate the surface. There is a a lot of useful information in the help.

In short, you will take your points convert them to a raster,  then take your raster and create the contours from it.
