To answer your first question - ${MACRO_EXTEN} is a macro-specific
variable.  It's the ${EXTEN} that called the macro, since using ${EXTEN}
inside a Macro would just give you a value of "s".

As for your second question, that's pretty easy to do.  If every outbound
call needs to be formatted in the format 1NXXNXXXXXX, you would do this
(again, untested, but should be good along with the macro I gave you
earlier):

[globals]
DEFAULT_AREA_CODE=555 ; swap with your default area code

[outbound-context]

exten => _1NXXNXXXXXX,1,Macro(OutboundDial,${CHANNEL},${EXTERNAL_CALLERID})
exten => _NXXNXXXXXX,1,Goto(outbound-context,1${EXTEN},1)
exten => _NXXXXXX,1,Goto(outbound-context,1${DEFAULT_AREA_CODE}${EXTEN},1)
exten => _011.,1,Macro(OutboundDial,${CHANNEL},${EXTERNAL_CALLERID})
exten => 911,1,Macro(OutboundDial,${CHANNEL},${EXTERNAL_CALLERID})
