Thank you so much, Michael, for your quick reply. With your help, problems#1 and 3 are solved.
The file, ppinc.php is huge. I found the topmenu(). When I tried to fix it, i almost destroyed the site. Will you please be a little more specific as far as the code to redirect the home button from the gallery to: http://www.mizikkreyol.com/index.html
For question #4, for the centering issue, i opened the categories.tmpl and i got lost. Will you please help me out.
I appreciate you help and many thanks
