Things I learned so far for smoothest (early/mid) IES experience:
1) Using your first Resonant Machine block to make Ender Tank Frames will make your life MUCH easier. A combination of Ender Chest, Ender Pouch, Remote Orderer, and Request Logistics pipe means having total access to everything in your LP network from anyplace in your base.
2) Renaming your Pouch and ender chest at a tool forge will allow you to have multiple "ender frequencies" within the same color code and allow you to have Named systems on your hot-bar. Example: "Inc." chest connected to a Request Pipe and "Sort" connected to a Quicksort or Extractor pipe, those two Pouches(along with the remote orderer) are amazing!
3) Start an automated Sieving line for EndStone and Soulsand ASAP. You will need the Draconium and Ghast tears (also process a LOT of Netherrack if you want Cobalt/ardite but Draconium is slower with NR).
4) Galgadorian will be a monster pain, Ghast tears, Slime balls, Brown Mushrooms, and Spider Eyes are all needed in HUGE quantities. (You need 54 Ghast tears to start ME)
5) Once you have a harvester set up, put your witch water -> Soulsand farm in it's range, you will harvest more than enough brown mushrooms while you are sieving for Ghast tears.
