Can I use P0.21 as a regular GPIO ? When I power the chip up, will it start correctly ? Is there any problem if I connect it to a LED and resistor ? How do I configure this port?

Hi
The P0.21/nRESET pin can be used as a GPIO, then is should not be a problem to use it for LED\resistor combo.
Here is a link to the nordic.infocenter whit the where you can find the pin assignment and GPIO list.
Here are some links to other devzone post regarding same issue:
