The toolbar preferences are saved in ~/Library/Preferences/com.omnigroup.OmniFocus.plist; the perspectives are saved in the folder ~/Library/Application Support/OmniFocus/Perspectives -- if you copy those to your 2nd computer, you'll transfer the perspectives and the toolbar along with them.

The preferences file does include information on syncing; I don't know whether copying it will mess up syncing. My advice would be to make a backup and then give it a try, but then I always keep three backups of my important data so I'm not too worried when something goes wrong!
