As for the speeds of ships in the older fluff sublight travel is a lot slower - in Imperial Armour III it takes 3 days to reach the system's sun (approx 1AU); in Execution Hour it takes Imperial ships days to reach the safe distance for warp entry.
With so much contradictory information out there it will be very interesting to see what the RT figures are.

The older fluff specifically mentions accelerations of 50 gravities on a merchant ship (Genestealer game). 40k fluff info has overwhelming shown double and triple digit gravities acceleration. There are some lower outliers but there are also higher outliers as well.
For those less science minded folks, a gravity refers to the force acting on an object on Earth, which is to say an acceleration of 9.8 meters per second squared. That's how fast things fall on Earth. It's a common way of measuring acceleration in science fiction settings.
