Well, personally, I wouldnt worry so much about geekbench scores..
Have your laptop do what you need it to do, and do it as efficiently as you need it to.
So if your messing with graphics and need 16gb ram, go for it, I only require 4, at times when im using a few audio apps at once I'd benefit from 8, 16 is a long way off for me.
SSD was a vital upgrade for me, as well as the hdd in a caddy, and a NAS drive in my loft on gb lan, I require lots of space for my music, but also wanted my apps to open quickly, and I hate waiting for an OS to boot, so quick start up was paramount to me.
Th 1080p monitor is an upgrade Ive considered for some time, but I wont do it until I have spare cash floating about.
As for the CPU, again, another upgrade I will do, however, its one of those upgrades Ill do once i feel my laptop is running at the speed of something out of date, and by then of course, much like your SSD theory, the prices will have dropped.
But basically, upgrade what you feel you need in that order as apposed to what will improve your geekbench score.
Good luck with it, I know you'll be amazed by the sdd, couple that with some more ram and CPU it will be great, if your looking for impact, and have the cash, do the lot in one go.
