Sighing.... the Help Documentation is hopeless, outdated totally. That main toolbar doesn't exist anymore, was there until CP7. It has been 'replaced' by that Big Button Toolbar on top of the screen that takes up a lot of real estate and cannot be moved nor customized. Some items are still in the Insert menu, but it has been stripped down a lot, you'll not find everything that can be inserted there neither. Just wanted to warn you. Only the pages about new features are really updated, but do not refer to other pages.
Workspaces are gone, at least in Newbie User Interface. There is only Classic. You can switch to an Expert UI that allows you to create custom workspaces but perhaps that is too early.
I am just wondering why you are trying version 8 and not 9 which is the most recent version?
