I agree that any form of "pre-cycling" is wasting your time. I have set up dozens of tanks, including my 115g which has been torn down and reset with new substrate and filter media more than once, and never mess with any type of cycling. Live plants are the best.
When I last did my 115g it was last summer. I put the fish in a 30g along with all the wood, just in case anyone wonders about that. I cleaned the tank, washed the new playsand and added it, added about 7-8 inches of water, siphoned that off (it was very dirty
), then filled the tank maybe half full, conditioned the water (to get rid of chlorine), then moved over the wood, planted it, topped up the water to about 4 inches from the frame, got the filter (with new media) running and the heaters, left it overnight. The only reason for this was in case the water was still dirty from the sand, but it wasn't so I then moved over all the fish.
In your situation, I would set up the tank, plant it, get the filter and heater running; leave it overnight to ensure no leaks, filter working, heaters correctly set. If all is good, add a few fish and gradually increase the fish load.
I have also used biological supplements in new tanks, more out of an abundance of over-caution. Seachem's Stability or Tetra's SafeStart. These are both live nitrifying bacteria. Sometimes I use these if I have a major fish load going in the first day.
