Any real requirements as far as processing power for your computer?

None. The printer does everything. All you do is feed it a gcode file.

Although in the case of this finger, you need to install OpenSCAD and regenerate the STL or 3MF files with the right measurements for you, and then you need to slice the parts to generate the gcode files to feed to the printer. So you do need a computer, but it doesn't have to be anything special.

I think most digital prosthetics utilize a rubberized silicon that kinda feels like a soft tire tread.

I've used Sika Biresin U1305 polyurethane for the soles of custom footwear I made for myself. It cures into a grippy, durable hard rubber. I would definitely try it on something like a prosthetic finger. It might be a bit too hard but the durability is really good, since it's good enough to make custom shoe soles out of.
