I'm missing a specification of the involved gerber formats. The scaling seems strange, I got ten times the physical size when reading the data to GCPrevue. Also the gerber files have arbitrary offsets, I would prefer the lower left corner aligned to zero. Drill data have been generated without an embedded tool table and have an offset different from gerber data.
I guess, Pads should be able to do better.
Apart from this points, the data look reasonable. If the PCB manufacturer is able to guess the right design size, align the drill data and add a tool table, it can work. But you can increase the chance to get it right by adding the said information and aligning gerber and drill data to the same offset.
