Capacitors for DC/DC converter
No, your selection is not okay. The datasheet recommends 660 uF  at each converter input, with less than 0.7 Ohm internal impedance at 100 kHz. Not every electrolytic capacitor can meet these parameters. You might want to employ an array of smaller caps to meet the 700 mOhm at 100 kHz requirement.

More, to ensure the advertised parameters (ripple level etc.) one 10uF cap is not enough. The datasheet suggests the following filter circuit at the output:



Please read the datasheets more carefully.
