I would personally put:

The fuel reg on left as it's closest to the reg

MAP sensor in the middle which i think is the only non-elbow type air fitting which comes straight out of the manifold, and is the factory position for, and closest to the MAP sensor too

Leave the fat oil breather PCV (positive crankcase ventilation - see http://www.burtonpower.com/technical...er_system.aspx for explanation) alone

Put your remaining lines (boost gauge/dump valve etc) using tees on the remaining take off

The order really doesn't matter so long as you have dedicated lines for your fuel pressure regulator and MAP sensor, as these can kill your engine if they come off.

Use new hose too. It's cheap insurance. Also, it wouldn't hurt to cable tie the ends of the air lines for extra security.
