Looking good Mick. Since you got such a bargain on the switch panel, I would strongly recommend you spend some of the money saved on a contactor. Essentially, this is an electromagnetic switch that will disengage the power in the event that you lose power to the lathe (e.g. a blackout). This offers a safety mechanism, as when the power returns the lathe will not jump back to life.
You then use momentary action push button switches to run the lathe. Given the buts you already have, I would use the key switch to isolate the power (very handy if you have kids), the emergency stop switch and the two way switch to select forward/reverse, and the momentary switch to start the motor. I would also use one of the indicator lamps to show that you have power to the control box.
Looking at the pictures, you actually need to get the switch body for the emergency stop and the push button. These are present on the key switch and the selector switch. They are available in normally closed (NC) and normally open (NO) and simply screw into place. You can gang them together where needed. If you know an electrician, they can get them cheaper than if you walk in off the street. Mind you, they are not that expensive to buy but they are a lot more than the two quid you paid for the lot!
