sorry to hear about this mishappen. I recognize it, since it happened to me a few years ago, also my daughter pooring thee (not coffee - but the difference is marginal - ) into an external keyboard. I took it apart and cleaned and dried it very carefully, but never got it working again. This was an external keyboard.
a similar failure occurred to other people with they laptop keyboards (and to me, without "using" any liquid). I presume - without knowing really the interiors of the laptop keyboards - that (1) they are read out in a kind of matrix (sensitive bars arranged in rows and (almost) columns corresponding to keys), which needs two layers of contact strips; and that (2) the layers are separated by plastic sheets.
Your diagnostics seems to imply that
1) there are still bad contacts (might be liquid where it shouldn't be);
2) the contact point has shifted ;
The latter could perhaps be due to liquid shifting the pressure away from the point where it should be applied.
What i would do:
Give the keyboard much time for drying - perhaps by removing the keys again. But there is always the chance that the temperature of the coffee, and the residues are causing troubles and might cause some keys not to function properly.
I think (i am not sure !!) you have a "unibody": i think it is "unique " in the sense that it has no screws (except at the bottom) - and no Firewire outlet. I have never opened my MB, but the only way i see for opening it is from the bottom (there are 4 screws at mine) - but i do not know whether it is advisable to open it. I would check via Phone with Apple before doing anything myself.
Hope this helps.
