What are the recommended decoupling cap values for these.

The cmos 555 datasheet mentions that they can be smaller but does not actually give any suggested values. So how small is 'small'?

And I have seen people using them for LM358 but my datasheet does not mention them.
 

Huh? A 555 is a timer, an LM358 is an opamp. Just use a 0.1uF or 0.01uF. It will be fine.
 

Hi,

Anything from 100nF to 10uF (the latter is rarely necessary), as the datasheet says, 100nF in parallel with 1uF works well; the same goes for the 358.
