The clean & press is fine. However if you have 6 reps to do I prefer to do 1 clean + 6 presses or 6 cleans + 1 press unless you are using it for metabolic conditioning.
If you are good at the clean from the hang, it should be fairly easy to learn the clean from the floor.
The main difficulty is that when you lift from the floor you will have the tendency to pull in a straight-line up, which will actually leave the bar in front of you, which obviously puts you in a bad position above the knees.
REMEMBER THIS: The purpose of the first pull in the olympic lifts is only to put you in the proper position to explode once you pass the knees. Those who screw up the lift from the floor often try to "clean the bar from the floor" instead of bringing it under control above the knees then cleaning it.
Start by doing a slow first pull. Focus on pushing your knees back when you lift the barbell from the floor and keeping the bar close to you. Once the bar passes the knees you accelerate.
If you are not comfortable with doing it as one fluid movement, sperate the two portions: (1) do the first pull from the floor to just above the knees. When the bar passes the knees you should be in the same position as you are when lifting from the hang. PAUSE in that position then lift. As you become more efficient, stop doing the pause.
Think of it this way: the first pull (floor to knees) is about precision, the second pull is about power.
