Try using the resistors that you have. They are close enough to the specified values as to make no discernible difference.
There should be no noticeable effect to the sound.
The upright diodes are shown as grey circles which I conclude means that the banded (cathode ) end of the diode faces up. If the circle was black then the anode would face upwards.
Good luck with the build and please let us know how you go. Cheers.
