Also having them up at a height that you are not bent over double trying to work on them.  I know I have changed these type tires in the past but don't remember having so much trouble with them. Funny thing is the one thing I remember having problems with was airing them up. None of the four I changed gave any problem at all airing up. I know they probably have some special tools for these small tires and wheels but hopefully they are not something I have a need for very often. With those tubeless tires, if I have a flat, I can usually get by plugging them.
