atmega328p outside the circuit board

a few questions.

1, what parts do i need if i want to use my atmega328p + 1 or 2 LEDs
outside the arduino circuit board?

2, is it 0.3" or 0.6" pins on the atmega328p? need one or two DIP Sockets.

_Rocket> eviltoaster: 1, resistor and capacitor for reset, 100n capacitor near each VCC pin, voltage regulator if you can’t provide 4.5-5.5V, electrolytic capacitor on supply rails, probably crystal oscillator (if you plan to use it)
<_Rocket> leds and resistors for them
<_Rocket> and 2, check in datasheet
