I could finally spin glowstone getting into the MV tier though it looks like you can skip a lot of MV which is nice. Need the Centrifuge and Electro for the dusts but it look like you only need the Assembler, Forming press and the Laser engraver so you can pump out the Advanced Circuits. Is this correct? Can skip most of MV like this?
Yes that is true, but my advice is to also get an extruder in the MV tier. Saves on a lot of material when making gears, rods, bolts, rings, casings etc etc.
From my experience redstone ore is not that uncommon and you will need it soon as it is one of the only good sources of chrome and ruby dust which is needed for the more advanced circuits. Chrome is needed in huge quantaties to improve the blast furnaces which you can get in decent quantaties from ruby ore as a byproduct when you have the HV macerator and a centrifuge of any voltage tier. So if i where you i would go out mining and hope for the best. If you can make the industrialcraft scanner i would cause it makes it a lot easier to find ores when you do branch type mining to look for veins.
