For the second "problem" I found a posible solution:

if key == 'z': #forward
	origin.setPosition(
		(origin.getPosition()[0]+(math.sin(vizmat.DEG_TO_RAD*origin.getEuler()[0])*0.1)),
		(origin.getPosition()[1]),
		(origin.getPosition()[2]+(math.cos(vizmat.DEG_TO_RAD*origin.getEuler()[0])*0.1))
	)
if key == 'b': #backwards
	origin.setPosition(
		(origin.getPosition()[0]-(math.sin(vizmat.DEG_TO_RAD*origin.getEuler()[0])*0.1)),
		(origin.getPosition()[1]),
		(origin.getPosition()[2]-(math.cos(vizmat.DEG_TO_RAD*origin.getEuler()[0])*0.1))
	)

and so on

Do you know a better way?
