What are upgrade patches and how do I know which to install?

When landing on the Mun, is it more fuel efficient to slow a bit all the way down or to burn hard at the end? When landing on the Mun, is it more fuel efficient to get into an orbit first or just come straight at the Mun and burn before you hit? (And if you understand the Physics, why?) Thanks JMG

I always run out of fuel. Sigh. After attaching to the asteroid and setting Kerbin as target, I do a burn of about 90 s to get in a good plane and into Kerbin's sphere of influence, but when I get there about 9 months later I don't have enough fuel to slow to orbit. Where should I maneuver?
