In the VST Source Code Archive ( http://www.u-he.com/vstsource ), 
there's an example VST ( "SyncExample" in processes category ). It 
might be useful in this respect (allthough I must admit it is not as 
easy to understand as I thought it was when I wrote it).

What I do is, I know "sampleFrames" and I chop it in pieces of 64 
samples and a remainder. These are my blocks. Then I do every step of 
my process (filters etc.) subsequently for one block. If everything is 
done I go to the next block. Hence I can outsource complex stuff before 
processing a block and do it only once per 64 samples, not for every 
sample. That's quite easy, once you get the clue...

Cheers,
