the speed advantages are such that I try to avoid spinning disks for OSs
wherever possible these days since the costs for SSDs have gotten so
low.
Andrei supports file-level copying, so I'll stick to that.
Yes, this is generally how I'd proceed. rsync existing filesystem onto
the new one, bind mount /dev /proc and /sys to the new filesystem, then
chroot into it, edit fstab on the new filesystem to point to the new
root (I'd personally use the UUID) run grub-install to put the
bootloader on the new disk, and then run update-grub. There are other
approaches to setting up the bootloader as well. It's best to do all
this in single user mode to avoid files changing while you're copying.
Then you'll want to change the bios settings to boot off the ssd first
rather than the hard drives.
