adding app browser in the dock

hi all,
well, i am very new to linux and slowly getting around…
i just installed the mac os leopard desktop on my suse 11.1
i would like to add the application browser to the dock but cannot find the path of this folder… any help?
also, i would like to hide the desktop icons. i opened the gconf editor and ticked off the volumes-visible as i read in a forum but to no avail.
thirdly i removed the home user icon from the desktop but want it back. it is not in the trash anymore.
thanks for your help!
