Add the OpenLayers.Control.ArgParser control and use the lat and lon
URL parameters to set the centre point on load.
If you want a default centre point without having to pass it in the
URL all the time, this code will work:
if(!map.getCenter()) map.setCenter(new OpenLayers.LonLat(-88.3,36.33))
(assuming that I have correctly interpreted your coordinates in the
example URL you gave)
