Some people (hello Psyche) feel that sending probes first would be rude, and might provoke an interstellar war, but it'd surely be much more discreet than sending a manned craft, wouldn't it. Some people say that it would be polite to send a message first, but that would depend, for a start, on knowing what their language was, and finding a medium that it could be sent on that they'd understand. So you'd need some preliminary reconnissance first, wouldn't you, so probes would very much be a sensible first move. Certainly, a probe from a civilisation that could, as I said, manipulate time and relative dimensions in space would surely almost certainly be intelligent in itself, I'd have thought; we can direct probes on Mars, but that'd be completely impractical at interstellar distances, so it'd be quite reasonable to expect the probs themselves to be what we'd think of as intelligent. So the Aliens might well be machines, although I don't expect they'd look much like C-3PO, although I like to think there might be some like R2D2, or perhaps K-9 off of Doctor Who.
I do not think initial communications would have to be a "Hello" but more of an attention getter, like the movies show, a set of prime numbers, something that is a sequence that is manipulated. I would suppose one would work from there. I think it would be an exciting and interesting time to learn and entirely new language, the likes of which we have never come close to hearing. Many heads would receive a vigorous scratching.
I am not quite as "both feet" as you guys that are chomping at the bit to set foot on an alien world, everything we have done so far has been slow and calculated, I think there is decades ahead of information gathering and much to be learned from observation and communication before presence is required. I think if we are going to do this, it should be one step at a time, ensuring the least possibility of failure. Comms is best bet to achieve this. Methodology and caution tends to favour success.
