What you apparently fail to understand is that how narrow you can go is determined usually by where the chainring will hit the chainstay. Therefore you will normally be able to go just as narrow with a road crank as with a track crank. On rare ocaisions you will find that the limiting factor will be when the crank hits the chainstay. This can only happen when you have the ring on the outside. A track ring where you can only mount on the outside will at best provide the same chainline as a road crank an may force you to push it farther out.
EDIT: now that I think about it with a 42t 144bcd setup the crank will likely hit first since the ring is barely bigger then it so the track crank is unlikely to even match the road crank in chainline.
Pins help derail the chain they are worse then ramps... you don't really want them if you are only running a single ring up front. There are plenty of 130mm cross rings that fit your speficication but not many 144 ones.
You should just get a road crank and use a cyclocross ring.
