i´d build up a tree farm, wheat farm, autocraftingtables, biogenerator and bioengines.
wheatfarm --wheat+dirt=humus--> treefarm --saplings--> biogenerator + bioengines.
in addition you have wood to transform or use ( transmutation ) and wheat for bread or transformation too.
should be fully automatic with autocraftingtables, redpowerpipes and buffer-chests.
