more pics .the motor config. is repeated on the far side .

Why do you have what looks like a 3:1 ratio on the screws.? Even with a 10mm pitch screw 2:1 is bad idea if your planning on using as wood router.
2:1 ratio will slow you down to around 5 or 6mtr/min max rapids and for woods you'll want to be cutting at that. 3:1 would be even worse.!!
Stay with a 1:1 ratio is my advise if your cutting woods.

Regards the motors then it's preference thing mostly 2 x 3 or 4Nm 23's will easily handle 65Kg. I prefer single motor with belt for accurecy and piece of mind reasons but I'm equaly happy to use slaved motors provided the correct drives and precautions are used. Slaved motors work ok but I would only use them provided you have Digital drives that can detect stalled motors or have fault output so you can E-stop the system.
Digital drives have made slaved motors much safer in my opion with less stalling as they handle current so much better and can easily detect for stalls. They also dont loose steps as much as the old drives did.
