Shannon,
Great ideas to have the facts straight & to have observed the employee. Another tool I have used in these situations is the acronym, SBI--situation, behavior, impact.
S-situation; describe the situation as you see it happening
B-behavior; describe the behavior that you have observed
I-impact; describe the impact you feel their behavior is happening & help them to see some possible unintended consequences of their behavior.
Hope this helps,
Ryan
