Usually people work towards some system of auto-processing your ores. Try for a pulveriser and induction smelter/powered furnace, and a hobbyist steam engine for early power (needs water!- don't let her run dry.)
Also make a few stone sickles and a hoe. Sickle+grass/leaves is awesome, and set up a small farm for food.
I would say the "most potential" goes to GregTech with the new Industrial Grinder and other changes from what was in the Beta A pack. It depends on which pack he's using. It also depends on what exactly Shiny Ingots will be used for eventually in Thermal Expansion, because those will not go far without throwing pretty much everything into the Induction Smelter.Now, processing automation is easiest with thermal expansion, but has the most potential with factorization. You will be blending machine sets, don't worry about it, everybody does.
