simple project for newbie

Hi everybody.
I'm not speaking english very well and i'm a perfect newbie with arduino.
I'd like to realize a basic project which consist turn on/off a led by wifi with osc protocol.
I found some information but i need a real support to start.
I bought a esp8266 card , a led a breadboard ...
I'm looking for informations about how to power the card , the led, and how to plug all.
For the software way. I think i can manage it alone. Thanks.
