The 100nf to 1 uf cap is a bypass cap. Typically these are ceramic, but could be tantalum or could even be a parallel combination of the two. I'd probably use a tantalum electrolytic there. The value isn't critical. Capacitor values ad when in parallal, so a 0.1 || 0.47 is equivalent to a 0.57 capacitor. Tantalum capacitors are polarized - pay attention to polarity. Ceramic generally isn't. Metalized Polyester aren't polarized, but sometimes it matters .
The 1 uf capacitor should be a metalized polyester with a better tolerance.
Any voltage greater than 2x the supply will work within reason.
I only got one decent hit at digikey:

Film cap, under 50 V, 1uf, +-5% tolerance (timing circuit). Filling in your country would help me.
