It seems that u r not log-in as ROOT. So u don't have to modify any thing except ur HOME folder. Ur desktop is under ur HOME folder. So u can copy files there.
If u wants to copy files to somewhere else, try to be ROOT / SU & copy.
for ntfs partitions,installing ntfs-3g is the way to get write permission.
yes,but do not login as root instead use a shortcut for Nautilus as follows in ur panel or use alacarte(in menu System>preferences>menu layout) to make an entry in Applications menu.
u get a dialog asking to give local passwd to get root nautilus.
do this.but never login as root.
edit
h! u use kubuntu,so make a menu as below in desktop,
now u can browse through ur entry with full "777" privilages
