To save hotbars, macro's, gearsets, and UI you open up the FFXIV Launcher, click the Config button, and use the Back Up utility. It's a good idea to use this utility every month or so to prevent you from having to redo all of your macro bars, gearsets, UI, etc if something happens.

Simply copy the file it creates to your new SSD; then use the Back Up to restore your settings after your fresh install of the game.
