I think you're on the right track, although it should be noted that plants need above all the other nutrients, the carbon in Co2.
Not like using 20~30 PPM but enough to help the plants quickly transition from their former growing conditions, closer to 5~10 ppm, depending on the water's KH.
Keeping the tank at neutral pH will make the slight amount of Ammonia have a larger ionic ammonium level and plants preferentially use Ammonium over Nitrates. The natural decomposition of the plants dead leaves and bio-muck will add some ammonia/ammonium to help start the nitrifying bacteria. It's a balancing game, but it's not something you need to be obsessive about.
