SC tree farm > line of sawmills > solid fuel LP36 boiler = all MJ needs satisfied.
Once boiler gets up to temp you will very quickly be swimming in excess wood, so :
Planks > array of IC generators > MFSU = 10 EU/t x however many generators you have.
We have a wall of 50 generators taking the excess wood = 500 EU/t 24/7. Taking into account night time cycle and rain, that's way more than what a HV array will produce and can be knocked up in about 15 mins assuming you have a reasonable supply of tin and iron (+ some copper, rubber, cobble and a bit of redstone). If your boiler is running on solids there is simply no point in making a steam turbine as you're just adding about 3 extra steps into the process to get the same end result (not to mention the crazy amount of steel needed for the rotor and the babysitting for when it breaks every other day).
Really nice setup! I've been hooked on lava for a long while and I've been thinking about something similar to this just to be different.
