Hi there, seoskunk:
I have to ask this. First, why do you think you were pandalized in the first place? Could you describe the general nature of your site?
You mentioned you removed 16 thousand pages, which I am assuming was thin content. Could you describe what type of content was on those pages? What type of content now remains on your site?
I know this isn't an answer to your question on whether to block googlebot or not, but hopefully this will give us all a bit more detail and then we can make a better suggestion about whether to block googlebot or not.
