I think that's right, assuming /dev/sda is the boot drive (not necessarily the same as the one on which your /boot directory exists!). If you haven't made sure that the stages matched the rest of grub in the past, I'd suggest being very careful in setting it up, but do it, and then perhaps not upgrading grub again unless there is a very good reason. The stable grub series is about the last thing for which upgrading makes a difference, I would think. I did that for a few years, but now instead I keep DONT_MOUNT_BOOT=1 in my make.conf so that grub doesn't actually affect my boot process unless and until I want it to.
