Here's what I do, and it has worked well for us with no stink or build-up or anything. I run a pre-wash cycle on cold, and then a hot wash with a double cold rinse. I use whatever detergent is on sale, usually the store brand, but I use a very small amount (less than half the usual recommended amount.) If you can't run a rinse cycle, maybe you could soak at home first, or just rinse poopy diapers first? I find that without a rinse they sometimes smell a bit. Then again, if your son is still exclusively breastfed, even that might not be necessary-- that poop doesn't smell like solid-food poop does!!!
I don't bother with vinegar or baking soda or anything like that. If the dipes start to get a bit stinky, I just do an extra hot wash. One time I boiled them, after DD had a virus and we had bad stink, but that was a special circumstance.
I guess I'm saying I don't think complicated washing routines are really all that necessary, unless you begin have issues with stink or buildup.
