Grub2 default boot

SuSe 13.1
I (rather my wife) would like grub to boot to my win7 partition by default after the 8 second countdown.

My fdisk -l

Disk /dev/sda: 500.1 GB, 500107862016 bytes, 976773168 sectors

Also, when I boot SuSe 13.1, I'd prefer to see all that text scrolling by than a background JPEG.

Thankin' You!
