New user problems!

I just installed NetBSD 1.1/Amiga from the Gateway II CD-ROM, and I'm having 
some problems...

1. Is it possible to get NetBSD to verify my harddisk after a newfs and map 
map out bad blocks on the disk?

2. How to I get NetBSD into a PAL screenmode?

3. Is it possible to get colourfull directory listings?  (A la Linux.  :)

4. (Very aesthetic, I know...) Is it possible to get white text on a black 
background?

Thanks in advance...

Jim
