yes, turbocharger -> intercooler -> bov -> maf -> intake
or turbocharger -> bov -> intercooler -> maf -> intake
there are guys who argue that having the bov on the coldpipe side is 'better' because it vents off denser air but it's kinda a moot discussion...I've ran it both ways and never had an issue with it on the hotpipe instead
as for distance this can affect things...the forums say to place the maf at least 20" from the throttle body, but from personal experience you can place it less than a foot from the throttle body without any issue...I usually have mine about 10-15" from the throttle body
the thing that could affect the MAF the most is the distance between the bov and the MAF sensor...when you discharge the air in the pipe it can cause a disturbance in the air that -could- mess with it's reading and cause it to stall when you come out of gear...I haven't ran it close enough to the MAF to say that I agree or disagree, but the logic is sound...I'd say, depending on the type of bov you have, at least 6-7" from the MAF would put you in the range of no worries
you might also consider taking the piping to a welding shop and having them weld it together rather than having a bunch of extra, unnecesary couplers...you'd be surprised at how cheap it is to have things welded together if you do the mockup yourself prior to getting it welded...typically anywhere from $40-$100 depending on the shop....be sure you have matching metals though (obviously) and if you have alluminum be sure to take it to a shop with a TIG welder
