I wasn't even planning on landing on the Mun, but I got lucky with a quick encounter, and thank Jeb I still had some fuel left for landing.

Idk if you figured out how to get to the Mu. without getting lucky with an encounter but I figured this would be useful info for the rescue:

Get into a 80km orbit around kerbin (try to make it circular ish, a few thousand meters won't kill you). Rotate your view in map mode so the mum is on the right side of your screen and a line between mum and kerbin divides your screen down the middle. On the part of your orbit closest to the bottom of your screen (like the bottom of the circle in this view), create a node and pull the prograde thing (circle with 3 bars, not the x which is retrograde, prograde = burn forward, retrograde = burn backward) until your apoapsis reaches a point where you get a min periapsis of 40 ish (your preference really). Then just land like you would for kerbin.

For getting back, get into like a 20 km orbit around mun, burn forward so that your path away from mun is in the opposite direction of orbit, and then modify your orbit once you're in kerbin's sphere of influence so that you come down through the atmosphere. Don't come down too hard or you might burn up and don't forget parachutes! Good luck :)
