First of all, find a large underground lake near your mineshaft. Dig a tunnel so that it all falls down your main mineshaft and collect it in a basin of dirt or stone at the bottom. Find the nearest lava lake below the basin and dig a tunnel to it, and mine all the obsidian that forms. You can then make an obsidian skull, so you can safely stand on Hellstone while mining it without taking burn damage. And with the Wall of Flesh, you don't even need to have Molten Armour, all you need to make is a long bridge of dirt and stay as far away from it as possible. I did it my first time in Demonite Armour with Demon Scythe and Thorn Chakrum, keeping it at the very edge of the screen. Don't try to melee it.
