It isn't possible according to our current scientific understanding, and
as Drexler explains, you can't predict *scientific* progress, so we'll
have to contend ourselves with the lightspeed limit in rational
discourse.

As you noticed, that isn't really a problem in itself--besides, the universe doesn't give a damn whether we like its laws--but only due to limitations of our bodies. Let's face it, homo sapiens is ill-adapted for space travel. We are too short-lived, we can't go easily into suspension, we could use better resistance against radiation, etc.
I think interstellar travel with present-day humans, as taken for granted as a convention by much of the ScF genre, is a pretty silly and unrealistic idea. If we're going to the stars, it will be either a much changed version of us or our mind children. Watery meat bags it ain't gonna be.

Assuming a scenario of uploading into some convenient technology, why should it be a pain? If you can't occupy yourself for a few years (decades, centuries, millennia, ...), just go into suspension. Sleep. Personally, I have a lot of things to catch up on.

If you allow yourself to get bored, it's your very own fault.

I guess this is a general question, that isn't really related to interstellar travel at all.
I dunno. How could *we* know?
