My new Blitz BOV is vented to the atmosphere.  It's really not as much of a problem as people say it is.  The ONLY time I have idle issues is when the BOV loses some adjustment and gets too loose (I need a locknut for the set screw....).  But it's up to you...recirc is better for the MAFS.

As for boost gauges...I would NOT get an Autometer if you need extreme precision.  Get something like a Greddy or Blitz or Defi or something.  My Autometer loses adjustment all the time.  I basically just use it as a "guesstimate" and it'll tell me if something's WAY wrong.  But to use it to tell me if I'm at 6.5 or 7 psi?  Useless.

I'm not sure how that wastegate setup is going to work.  Are you using an adjustable HKS one or something?

Pivot seems to make decent stuff.  However, I'd say skip the turbo timer and spend money on a NICE boost gauge or something else.  Turbo timers are really pretty much useless.  If you just got done running the piss out of your car, just drive around the block before you park it.  Or just sit there and let it idle before you shut it down.  It just seems like a waste of $100 (when you're on a budget).  I think it's something you can get later.
