Ok simple rule of thumb with layout is to keep mains voltage items/cables far away from Signal wires much as possible. Obviously at some points they will have to meet but reducing how close the wires and components come together will lower chances of electrical noise interference.
Regards the wiring design then just keep it simple don't go too crazy with the safety side. Many folks go way OTT with safety buying expensive Safety Relays when all that is needed is simple Relay driven latching E-stop circuit.
Ideally, you want to use 24Vdc for the Safety circuit and limit switches,relays etc as this gives greater immunity from noise interference. Can use 12V but 24V is best, avoid using 5V if possible.
Also, for new builder it's a good idea to build control in stages rather than wiring every thing at once only to find out something wrong at switch on and then struggle to diagnose where gone wrong.
If you give detailed list of all the stuff you have I don't mind drawing you up diagram.
