Fly towards Sirius for about 36 million miles then take a quick left. It's right there you can't miss it! lol

Once launched from the moon, you need to get into a Hohmann Transfer Orbit. The Hohmann orbit is one that is tangential to both (in this case) the orbit of the moon about the sun (yes, that's correct) and the orbit of Mars. (In effect, you would be wasting valuable fuel going fast enough to carry you farther out from Mars).
For an Earth or Moon Hohmann orbit the bodies must be such that in about 260 days Mars will intersect the orbit of your spacecraft (that's the most efficient time and distance).
When you reach Mars you will either descend directly or go into orbit, probably the latter, because there is no need to land your entire craft--you'll leave much of it behind, as we did in the Apollo program. To enter an orbit around Mars you will have to perform a braking maneuver with your rockets, in order to slow you enough for orbital velocity.
Once orbit is achieved and a site selected, your landing craft will separate from the main craft and begin a braking maneuver. At first this will be by rocket, but when you begin entering Mars' atmosphere you will allow it to assist you (bring along a heat shield!!) and later a parachute. When you get close to the surface the parachute is jettisoned and the rockets will complete the landing process.
I hope you brought a lot of food. To get back from Mars you have to wait over a year and a half for them to get into proper position for the return Hohmann orbit.

Actually, getting from the Moon to Mars would be much easier than going from the Earth to Mars. It is one option than NASA is considering for eventual Martian exploration.
You probably need to get there with a minimum expenditure of energy, and hence a Hohmann transfer orbit would be appropriate.
You can hone your piloting skills using the Orbiter simulation program, available at www.orbitersim.com
Good Luck

Turn left at Jupiter, you can't miss it.
