I made a thread on this over in Aviation and Space. I was having trouble too orbiting but I was trying to build my rocket too big. Start small and work your way up. Obviously I hope you are using the Map/Orbital view by hitting the "M" key. The orbital basics once you get up are that you effect the opposite side of the orbit:
To increase periapsis : You have to be at apoapsis... speed up pointing in orbital direction (indicated by the empty yellow circle on gyro instrument)
To increase apoapsis : You have to be at periapsis... speed up pointing in orbital direction (indicated by the empty yellow circle on gyro instrument)
To decrease periapsis : You have to be at apoapsis... slow down by pointing in opposite orbital direction (indicated by the yellow circle with X in it on gyro instrument)
To decrease apoapsis : You have to be at periapsis... slow down by pointing in opposite orbital direction (indicated by the yellow circle with X in it on gyro instrument)
Adjusting an orbit is a series of, point toward or away from orbital direction from either apoapsis or periapsis, and doing slow burns (sometimes literally bumping the throttle). Use the time acceleration to move between the apoapsis and periapsis.
***Also, remember that the faster/further your orbit the faster/further changes are made. While at 300km orbit, a 1-2 second burn at lowest throttle can be 10+km. When you get to 2,000km orbit, that 1-2 second burn can be 100+ km. It takes a whole lot of energy to break gravity, but to maintain or change orbit, it takes very little. I think it takes less than 1 fuel tank to get from a ~200km orbit to the Mun (11,400 km).
