are the capacitors circled in red electrolytic? can i use electrolytic capacitors? can i use 1000uf ones? i have loads. i am using 4 on one circuit board, can i use one 1000uf capacitor per rail for all of them?

where do the input capacitors go? after the potentiometer? where the blue circles are?

Yes, you can use 1000uf electrolytic, but bypass them with 100nf poly or ceramic near the op-amp pins.
I think you only need one input capacitor, after the pot.

are the capacitors accross the rails really neccessary? (on the DRV134 on the bridge and parrellel circuit) if they are, what are the ideal components? (type and value)
