No, that is a myth. You just cannot put the system drive on an extended 
partition, it has to be a primary partition. If that is the first non-Linux 
partition Windows will name it C, anyway, as it just ignores partition types 
it doesn't know. But, as I said, the letter doesn't matter.

No, see above, but really, it doesn't matter at all. Windows isn't that dumb.

No, I meant: why then reinstall grub? No need for it. You just change 
grub.conf. If you want to use a second disk because of drive numbering: no, 
you don't need to do that. If you want to do it for other reasons, like space: 
go ahead!
