1. How do you efficiently and quickly get ender pearls? Or do you just use A philosophers stone?
You can plant ender lillies or use a phil. stone. By the time you get to mid-end game you can use an autospawner to make it for you. 2. Other than a mining laser/precharger, what is the point in having a 20k + rf/t reactor and tons of resonant energy cells? Do big manufactories use that much power?
There really is nothing in the game that uses the same amount of power for a mining laser.. Maybe if you have an huge processing plant that runs on ME because it can draw a ton of power. 3. Based on previous question, do you have big factories creating/pulverizing/smelting items? If so, how to you get a consistent input of materials? Do multiple quarries do the job?
I personally use ME with my pulverizers and they are attached to redstone furnances. ME Pre. Export->Pulv.->Redstone->Basic Import.
I think 6 of these should be enough to handle quite a few quarries. Later on with a laser drill you need to take account of those pure block form items i.e. Diamonds/Redstone. Nether to regular ores..etc 4. How do you get shiny metal efficiently? Platinum is rare in the nether, and the 10% chance from pulverizing ferrous ore is annoying. Is there any way to make it more efficiently?
Be very efficient with this.. Go to the nether get some nether redstone.. heat it up then pulverize it.. you will get cinnabar and use that in an induction with ferrous ore, you will get a shiny every time.
You can also use lasers later to do this for you instead of finding nether readstone. 5. Any easy way to quarry in The nether? So annoying constantly watching it to eliminate lava.
Use a quarry with ice blocks. Break the Ice then you will have water that does not disappear? 6. And last, but not least, could you give me any tips on what I should be doing at this stage? What mods to be using?
What stage are you at? First I would try to figure out how to get enderpearls(very important for end game).. You could try overworld quarrying or in the End. Eventually you can build AS reactors or you can build a bigger BR reactor for energy. A good source of nether quartz should also be considered or you have to spend a ton of time in the nether mining those.
I think that should cover most of it. Try to get a better suit, it will make your life easier without the fear of dying. Autospawner + cursed dirt + Grinders are great. I am currently using thermal expansion ( red stone components, magmatic dynamos and a small reactor, various machines), modular power suits (low-mid), buildcraft (engines, pipes, quarry), and probably more that I can't think of atm.
