Is it leaking or low on refrigerant now? You want the system to be leak proof before adding a new drier. If it does not leak now, recover the charge and change the drier. Vacuum the system down and add your refrigerant.

Yes you will have to vacuum the system and yes you want to be sure it is leak free before adding refrigerant. Air left in the system will cause all sorts of problems and if you try to vacuum a leaking system you will pull air into it. System needs to be pressure tested for leaks not vacuum tested.
