Try BC557 for the BC157.
10µF and 0.4µF are standard values. Any electronics distributor will sell you that. Instead of 0.4µF you can search for 400nF, that is the same capacitor.

BTW, do you mean 0.04µF as required by the second schematic? That would be 40nF. You can use 2*22nF in parallel instead without much of a difference to the circuit.

It is not unusual to find that E-6 values for capacitors are easier to obtain than the E-12 series.

Having said that, both 0.039 and 0.082 are in the E-12 and not the E-6 series.
