To calculate area - (shapeflie file) in QGIS, Have a look on the Vector (menu)->Geometry Tools -> Export / Add geometry columns. You will get a new shapefile with area and perimetre columns Simple hack for acres; Open dbf file of that shapefiles in LibreOffice / OpenOffice add a new columns for arces and just just conversion from units to acres. I think you can add column as well in the attributes table and add the formula for conversion tor default unit to acres. Re: aerial photos, you can use georeference plugin (C++ plugin - standard /default installed by QGIS to georeference those photos. It easy and simple to do georeferencing in QGIS compare to MapInfo and ArcMap.
