You can do all of it in the include file, but everything which is before/after 
the include file will not be in the buffer.

Remember also that pages which takes long time to generate, may cause time 
outs when using buffers. IMHO don't use buffers if you really don't have a 
good reason to use them, just see to that you have proper error handling and 
your functions returns the generated content instead of using echo/print.
Those times you have a area where you know there will be issues of long 
execution time, just see to generate some output once in a while.
