Build a Website

Hi Im currently building a prestashop website and there is a few little problems im having which i need help with, they shouldn't take too long and im sure are small problems its just beyond my scope to fix. They are listed below in order of importance. 1. I cant my friendly URLs to work, for subcategories to work. I have a module installed that uploads 3000 products to my website automatically and i think it may be this. With the URL rewriting parameter giving each url spaces rather than hyphens. Thats what i think is the problem anyway and i dont know how to fix it. 2. To let me know why and possibly help with the logo in the top right of my website is supposed to have see through background, and it used to. It is loaded as a png image but since iv upgraded to a newer version of my template it no longer works. the template still supports see through png images as the original was on the new tempalte before i changed it. 3. Also within my modules in "other modules" the Templatemela - TopBannner, when enabled for some reason displays in the middle of the website all of a sudden and i cant seem to fix it. So in summary i need my Friendly URLs to work thoughout my website, my logo to have a transparent background, and the TopBanner to appear in its original place, in the empty space at the top centre, and the top banner to also have a transparent background.
