there are many different ways that lead to Rome... or to Barcelona in your case, Eduardo.
stitching and stacking or stacking and stitching are the two families. <http://panospace.wordpress.com/2008/10/08/exposures-stacks/> since most tools can't handle yet the 360° seam nor zenith/nadir for full sphericals I use stacking first. It has also the bonus of being faster. For true HDR it does not really matter because the stitched result must be tonemapped and the tonemapping tools don't handle the seams...
