hi
I guess I can help you with 1 and 3:
your first serial ata drive is sda, second sdb, etc
now you have to know which partition your windoze is on, e.g. sda1
sou you have to put something like
other = /dev/sda1
label = Windows
table = /dev/sda
I'm not sure about the RAID though, maybe it could be different there
3:
you have to manually set the right frequencies in your /etc/X11/xorg.conf
Maybe you should refer to your monitor manual for the frequencies.
and then you look for options about the resolution in xorg.conf
I think it is quite well commented
good luck with 2
hope that helped
