When could space travel (including FTL of any kind) and other tech be common?

I'm looking for some data to create my own sci-fi setting, but I want to base it on real world as much as possible. Also, I don't want to come up with any arbitrary year like 3290 with no background on it.

I thought a lot about it, but I still can't find a good answer.

What I want is a setting where the following apply:

• Humans can live outside Earth. Deep space stations are minimum, colonies on habitable planets are welcomed. I do not expect terraforming to be common,
• Faster Than Light travel is a thing. I don't care if it's BSG's FTL drive, Star Trek's Warp Drive, Alcubierre drive or any other kind of tech,
• Long range communication of any kind is possible. (Almost) instantaneous communication should be possible within one planetary system, and possibility of interstellar fax/emails would be nice,
• Nothing prior to current date and tech level can be altered,
• Tech progression is logical and feels natural

Question is: If I want to create a sci-fi setting that meets all conditions above, what year would suit it best? Any additional arguments are very welcome as well as science/physics background for tech.
