The character-specific hotbar/gearset/HUD settings are located in C:\Users\username\Documents\My Games\Final Fantasy XIV - A Realm Reborn\FFXIV_CHRxxxxxxxxxxx\, with the exes being a unique character ID for your character. Copying that folder alone and placing it in the exact same location on your other computer should do it. I tend to log in once on the character before copying the files so that the folder's created by the game, then I just copy everything into the folder.
