Not rubbing alcohol, no! And no to the coils - they should be ready to vape.
If you want to use alcohol, you need Isopropyl - it evaporates clean...you can get it on Amazon.
Or you can use Grain alcohol. Or you can use vodka!
But honestly, even though I have that stuff, if I want to wash a new tank or dripper, I use hot water and dish detergent. Then rinse A LOT.
There have been some new tanks that had a "machine oil" flavor to them through cleaning, boiling, and alcohol - but finally came clean with a little soap!
