Making Ubuntu KDE-like?

[Ed Sutherland]

I've decided to switch to Ubuntu Hoary due to its ease of installation 
and hardware detection, but have a few questions on how I may make the 
Gnome desktop environment look/behave more like KDE. (I know many 
believe KDE creates a sluggish system -- I prefer the quickness and 
interface elements of Gnome, but KDE has some wonderful productivity apps.)

Is there a crystal-like theme?
Is there a K3b clone for burning data/audio CDs?
Is there a FAQ on enabling Java, Flash and MP3?
How about Adobe Acrobat 7?

Thanks.
