Small Oil Leak. What Else Should I Replace When Going to the Mechanic?

My CL has developed a small oil leak from the oil pan area. :yuck: At least that's where it's dripping from. Don't know the exact cause of the leak yet, but I suspect it has something to do with me running over a curb the other day on my way home. I'll find out tomorrow at the mechanic.

But what else should I replace in addition to the problem, once found, when I'm at the mechanic tomorrow? What are some common issues with oil leaks with this car?

Thanks!
