You wouldn't want to umount /boot or /var until after you copy the files over 
to /dev/sda2.

Instead of this approach though, you'll probably have a better time if you 
take this opportunity to start using LVM.  Leave /boot alone, copy /home 
and /pr0n(?) to /dev/sda2.  Then make a new partition table on sdb, make an 
identical /boot on /dev/sdb and either dd or copy /dev/sda1 there.  Allocate 
the rest of the disk to LVM, carve it up as you choose, and copy the files to 
the LV's.  Update /etc/fstab, and run install-grub, and you're set.

This doesn't need liveCDs or single user mode, you can just boot right into 
the new system.
