I am new to FTB so I'm curious: do you use that lava as a power source? If so, do you use it to power a steam engine to power your machinery?

I am looking for a power source myself. Per the quests I am now making an oil refinery but all of the wells are quite far from my base, so I am wondering if the lava crucible furnace would be a better choice in stead.
The mods that have early game lava power generation aren't in this pack. Mekanisim has been mentioned but as far as I can tell, it is much later game than either you or I are at. If you go the biomass/biofuel route as you mentioned, you do need lava as a secondary input for the engines unless that's changed since the last time I used Forestry engines.
Air essence in a crucible furnace makes steam and crucible furnace is powered by lava, so in theory that is an option. If it's not disabled, Botania also has a mana-to-RF generator, so in theory you could use lava to power thermalilies to make RF, but the nature of thermalilies and the lack of an easy power storage battery (that I can find) might make that inconsistant.
By the way, the auto-eject of liquid out of the crucible furnace into BC pipes was happening at a snail's pace - the furnace would fill and get backed up. I had to put an engine on the pipe.
What I don't have yet is automated plant harvest. My understanding is that I either need Thaumcraft golems (I haven't unlocked the Thaumcraft quests yet) or Forestry orchards (I don't have a way to supply fertilizer yet).
