I'm still quite the dummy in ftb so I didn't even understand what half of those machines do. The way I see it though is that you're telling me to focus on making machines that will make the production of ores and minerals much faster. Perhaps you could give me a simple guide or overview of what machines to build in order from 1st to last? It doesn't have to be every single machine in the game just the few common ones to get me started.
Ah, gotcha.
The reason I recommend machines from Thermal Expansion is that they can be configured to output and receive items automatically. Other machines require engines, timers, gates, or other contraptions to move items around.
Basically, first look up the pulverizer. This will take raw ores (like iron, gold, copper, etc.) and turn each ore block into
two of that type of dust. When you open the pulverizer interface, click the green tab and switch the machine to accept items (blue) from the top side, and to output all items (orange) to either the left or right (whichever side you want to put your furnace on).
Next, build a Thermal Expansion furnace. You will know it's the right kind of furnace if it uses a machine frame in the recipe just like the pulverizer did. Click the green tab again and set it to accept items (blue) from the side facing the pulverizer, and to output items (orange/red) to the opposite side. On that side, place a chest to hold all your fancy new ingots.
Finally, place a hopper on top of the pulverizer so that it can feed into the blue input. This allows you to come back from a mining trip and just dump all your ores in at once rather than sitting around waiting for each type to finish. If you feel like one hopper isn't big enough, just slap another one on top of the first one!
Finally, you need to power the machines. I suggest Thermal Expansion steam engines (there's more than one kind of steam engine - this one has a redstone transmission coil in its recipe). For now, you can just feed these with coal manually, and stick water in them by right clicking on it with a water bucket. Place a wooden conductive pipe on the engine, and then run golden conductive pipes to your machines. Give the engines a redstone signal to get them running and you should see the energy in your furnace and pulverizer start to build up. If the machines get full and the engines run too long though, they'll blow up - so keep an eye on that! Also, if they ever get jammed give them a whack with a crescent hammer.
That should be enough to get you started. But in all honesty, the only way to really advance without someone holding your hand is to get really good at scouring wikis and/or watch lots of Youtube videos on FTB. I personally prefer the latter method. Direwolf20 does some excellent and very popular tutorial-style Let's Play series. But don't limit yourself to doing everything exactly like he does it. (Or like I've outlined here, for that matter!) Do something fun and creative!
I hope that helps!
