You are correct about the speed of light not being constant *if* you
assume that the distance quantity gets warped as your speed approaches c.
One of the big problems with relativity is that we measure c as a rate which
equals distance/time. Because of this relation, we cannot be certain(AFAIK)
whether it is time or distance that becomes warped at speeds much greater than
our own. The way I have always looked at the problem is analogous to using a
flashlight to look around in a fog bank -- we can only see so far around
ourselves before the range of our observations begins to break down. Light
speed just happens to represent an upper limit of observation relative to
our own speed.

Current theories do not support backwards time travel unless you
happen to be a tachyon particle(these particles travel faster than light and
live backwards or so it's claimed anyways). Forward time travel would be
possible, however by nearing the speed of light.
