はるばる just means from afar, over a great distance etc. which I am sure you have been able to look up. The particle と attached here, can mean different thing depending on the context, but if this is all there is given, then I guess all と does is to indicate there is a reaction or something coming after it. ie 言う 思う ← both pretty common, but it there is an endless amount of things that can be attached…
It is hard to see without the context though, so if you provide some more info it might be easier to help :)
As for your Question Joel, I have no clue :p
