If I drive the CH_PD from an other circuit, is the capacitor still recommended?

In general capacitor is for debonce purpose.
Not nedded if You drive CH_PD pin by the logic levels without noise...

Hey,
I got the ESP-03 and planning to make a dev board with Reset & Program switch (some logic like hold program Button and reset the Board). For program mode i will make GPIO0 to GND through push button any suggestion for reset button/ logic.

Then, wire a normally open push button between GPIO16 and ground. Keep GPIO16 high thru a 1~10k for normal operation. And your board will behave like this:

As a bonus, deep sleep will be possible.
