I don’t have the Zelos 3, but the Zelos X (replaceable 18650 battery) and I also have a Nautilus 3 tank. This is also perfectly fine as a starter kit. Later, if the world of vaping appeals to you, you’ll go deeper and deeper down the rabbit hole anyway, with new mods, RTAs, etc. 
For the Nautilus, I definitely recommend the 1 ohm mesh coil,
