If its bumpy slow down. You don't speed up in a car when you spot a speed bump! Manoeuvring speed (VA) in bumpy conditions should be the maximum not a target.
I had to cruise back from Hawarden to Cardiff yesterday through mountain wave/turbulence etc at 90kts rather than my normal 120.
Also, don't worry too much about maintaining altitude (unless of course close to terrain or the base of CAS or flying on a specific clearance). You are going to be bumped up and down a bit, just accept it in within say a couple of hundred feet of your target altitude rather than trying to constantly change aircraft configuration for climb/descent.
