Wing clipping is a personal choice. It can make training easier but it can also set you back in trust.
To get them back in the cage after letting them out, you can use a stick or ladder or something else they are willing to step on and try that way. If you have enough time in the day, letting them just go back in the cage on their own (i.e. to eat) usually works well too.
Also, if they're all white tiels, they're called whiteface lutinos. Albino is not actually a thing in tiels because of how their genetics work.
