As I've indicated before: to the extent that gravity interacts with this propulsion system, I want to use the tidal forces as a baseline. Actual gravity produces tidal forces; acceleration-based pseudo-gravity does not.
You still want to keep track of potential energy changes. Given that warp drives don't change your reference frame, counting PE changes in your drive inertial reference frame is reasonable.
If I'm understanding your numbers correctly, the speed limit at 100 AU would be 16,000 km/sec, or approximately 6% of lightspeed. At 1000 AU, this would increase to 6 times lightspeed; and at 10,000 AU, you'd be traveling at 600 times lightspeed. IIRC, that gets you into the Oort Cloud.
In general, the time requirement to go from distance X to distance Y is K*(1/X - 1/Y), where K is the time to go from zero to infinity; if there is a limit on dissipation rate as well as power production rate take the absolute value.
