The report of my EKG says I have a sinus arrhythmia - should I be worried about this?

No. Sinus arrythmias are very common, especially among younger people. They can be exacerbated by caffeine, strenuous exercise, drug use, even alcohol use. Check with your doctor to verify that your arrythmia doesn't also have any variations on the other elements of your electricl acticity of the heart. Your doctor will understand this. But you need to verify that there is nothing else going on.
No. Sinus arrhythmia is the slowing of the heart rate in relation to your breathing that can be picked up the ekg. This is because of physiological filling and emptying of the chambers of your heart in relation to the thoracic pressures in chest cavity.
Absolutely not. Many people have sinus arrhythmia. It merely means a variation in the beating pattern of the heart associated with breathing, and has no effect on you or your heart's health. It is mentioned in EKG reports for completeness, not because it has any clinical significance.

I perform an EKG and the result was sinus arrhythmia. Is this a normal condition?

Please Clarify. There must be a miscommunication here. Arrhythmia is a generic term to mean abnormal. There must be another word there to describe the specific abnormality. If there is not an 'arrhythmia' then normal sinus rhythm is a common way to say normal.

History of WPW and ablation. Now a recent EKG shows sinus brad, sinus arrhythmia and right bundle branch block. Is this a huge deal?

Only if symptomatic. Sinus arrhythmia is common in young individuals and not a concern. Sinus bradycardia is only significant if symptomatic (dizzy, light headed, passing out.) RBBB is relatively common and does not necessarily predict any significant issue. If you have no symptoms you don't need to worry about this.

History of WPW and ablation. Now a recent EKG shows sinus brad, sinus arrhythmia and right bundle branch block. Is this a huge deal?

Wpw. The best person to answer these questions is the ekectrophysioligist who did the procedure, but sinus bradycardia depends in how low tye rate is and whether the patient has symptoms. Respiratory sinus arrhythmia is a normal variant and right bundle branch block is isolation can be a normal vriant.
