I did pretty much what you plan to do. You need to have the "/boot"
partition on the SD-card and the "/" partition on your SSD.
I make my comments in you list below:

keep all partition on the SD-card. Modify
/boot/extlinux/extlinux.conf and change the corresponding items. Use
uuid-addresses to direct to the correct root partition on the ssd.
Boot the system and check if it correctly starts from the SSD and not
from the SD-disk. It it runs correctly, remove the /root and swap
partition from the SD-disk. Use GParted to resize the /boot partition
to use the whole SD-disk.
You will need the SD-card anyway to boot the system, but there is not
much R/W access to that partition except at boot time, so the speed
increase is significant.
I had to go through this process, because the /boot partition is too
small to go through a successful kernel update. "yum update" wanted to
update the kernel, it ran out of /boot-space and corrupted my system.
If you need more details, I can supply more information later today. I
don't have access to the system right now.
