The above "wooden" characteristics are the classic symptoms of a master cylinder that is too small a capacity/bore for the job in hand - it works but only at full pressure.
Although your caliper and master cylinder are matched (being from the original setup), the change from a 298mm to 320mm disc means more braking force is required to achieve the same level of friction. The stock master cylinder, from your description cannot meet the pressure required until it is nearly fully compressed. A larger master cylinder will give you more feel as their is a greater volume of fluid (and flow) to allow you to better control the hydraulic pressure with the lever.
Try pads with greater friction may help, but could make the "all or nothing" feel seem even worse and they may become "grabby" as well as "wooden". Worth a try though...
