The order then would be, disconnect drier, install new drier, vaccum out system, and then refill with r134.

Leave it alone. I wish R134a wasn't sold over the counter, what is going to happen when somebody who doesn't know what's going on hooks a can of R134 to the high side of the system?
Unless you want a serious case of frostbite, don't touch it. You don't go around disconnecting a/c lines without the proper equipment.
This is why R12 got banned, and R134 is going to be banned soon. People who don't know what they are doing are venting gas into the atmosphere and getting themselves hurt.
