Say I have a spacecraft with eight engines, orbiting Kerbin. Would it be more efficient to burn all 8 engines? or just as few as possible?

Alright, so I've successfully gotten to the Mun, Minmus, and Duna, all with three man landers. My next challenge for my space program is to get to Laythe, and eventually put a small base there. However, for the time being, I simply need to land three crewmembers there. I need some designs/pictures for a three man lander. Nothing minimalist. I'm not planning on landing on the water, so it needs to be something with enough fuel should I end up far away from my landing site.
