How to get Microblaze to control a DDS Compiler

I am a little confused by something.  I have a working design that I dropped a DDS Compiler into.  It works fine.  Now I want to use my already instantiated microblaze to set the POFF/PINC.  Since the DDS uses an S_AXIS_CONFIG interface, I setup an AXI4-Stream Data FIFO in front of it, and then an AXI-Stream FIFO in front of that so I could hook it up to my AXI Interconnect.

Is this the best way to handle this?  It seems a little clunky to me.  

Also, I have  couple of these running in parallel and they need to be in sync.  Is there anyway to kick these all off at exactly the same time so that they all start off on the exact same clock?
