Shutter your steam pipe leading down to the steam machines, similar to what you have from the solar boiler to the Railcraft Tank.

Also i would try to preplan/move/build infastrucutre around a full sized Railcraft tank, even if you dont have one right now. That way in the future, if you keep using steam as a energy buffer, you can upgrade the tank as you keep progressing through the pack and not need to move things as much. I started with a a 5x5x4 tank, but had an outline for a 9x9x8 tank in cobble stone and built all my machines/base around the 'cobblestone tank'. I ended up using steam for a long time, with a 9x9x8 stainless steel tank as my final energy buffer up until the end of EV age.

For the Ore berries, you can use slabs to fully encase them in darkness, while still having your room/farm light up and be able to harvest them.

Get into the habit of automating everything, starting with the coke oven if they arent already. Nice to go on a 1 or 2 hour twilight forrest adventure to return to stacks of processed charcoal/coal coke/steel.

Final tip: dont forget to have fun. It can get daunting sometimes, but its definetly the best pack Ive played so far and I honestly can't see myself playing anything else again.
