A propane torch will remove the "noxious" from your hardware. Its a coating. Throw them in the drum when you do your burn if you like. After my first seasoning everything was black and coated. The current trend of using BGE style intakes has been awesome for me. It bumped my available top temps, allows me to give my basket a shake if neccesary and saves me the annoyance of ugly plumbing hanging off my barrel. And the last benefit of easy clean out will not apply to you with the removable bottom but is wonderful for the rest of us.
A nice addition for your drum is to pick up some car tire valve stems- the kind that are bolted on. They are stainless steel and often in the garbage of your local tire store. This makes a 2" entry port(sturdy) for your thermometer and if you get 12" probes you can use it to check the various areas of your grill.
Get 'er done!!!
