What do you think?
Both Voyagers has already exceeded this speed.

For my own purposes, I'd go ahead and send the rover down. My personal attitude would be "what the hell." They'll find out about us pretty soon, anyway.
However, since any probe like that would likely be part of a much larger exploratory effort, the majority of the scientific team would probably want to sit back and study the civilization before we "contaminate" it with knowledge of our presence. Scientists are always doing that kind of thing.
Anyway, it would take decades if not centuries for a physical probe to get there, and along the way, we would be picking up evidence of civilization from long range spectrometry and stuff like that. So it probably wouldn't be a big surprise to us, and we'd have a lot of time to debate what we were going to do about it. They could very likely discover our radio signals a long, long time before the probe ever got there.
One thing we might do is drop the probe and give them specific instructions on how to build a good radio telescope, and where to look for us. Our radio signals are already reaching them, and that might give them a chance to find out who we are at the present and what we're up to. Then we can at least start some kind of communication with them, even though the response time for any question would be 10 years or so.
A more likely scenario is that our telescopes first spot a liveable planet, then an atmospheric chemical spectrum that indicates some kind of life or industry, then perhaps some basic radio signals coming from them. Then we can decide if we want to try two-way communication or not, probably using radio, since sending a physical probe is so slow.
Then there's always the notion that maybe we want to keep ourselves secret for a while, until we can determine if the aliens are going to be friendly or fierce. On this planet, the little creature who pokes his head farthest out of the hole is the one most likely to get its head bitten off. The same might be true for space.
