"Near c" will get the benefits of time dilation.

I disagree. Any vessel capable of warping is also capable of time travel. And I think the universe isn't going to allow time travel.
It may seem hypothetically possible based on humanity's current knowledge. But I suspect that if we knew more, we'd know that it wasn't even remotely possible.

I agree.

Interstellar travel will definitely be a one way trip for the colonists, but it will not take long from their perspective once time dilation kicks in.
Also, a human interstellar voyage would be unlikely to be to the other side of the galaxy. More likely, such a near-lightspeed journey will be to a destination much closer, like say somewhere within 1,000 light years of earth.
We will probably send out unmanned probes long before sending out colonists, and will therefore already know ahead of time whether a given destination is suitable for colonization.
Although given the fact that we're living in a metastable false vacuum, there may not be any point to our species spreading out and trying to flourish. We're pretty much doomed no matter what we ultimately do with ourselves.
