If all you want is to remove items, then holding down the command key, then mouse to the item, and click and hold (with the command key still pressed) and drag off the toolbar should result it the item vanishing with a poof of smoke. However, since your Customize function is greyed out I'm not sure this "normal" behavior will work.
Do you have a test user? If not you can create one in System Prefs/Accounts. Give the test user admin rights, and leave everything strictly at the Apple defaults, do not add any of usual goodies (login items, fonts, contextual menu items, and so on). Just leave it as Apple makes it, with default everything. Log in to the test account and see if things behave correctly.
A test user account takes up scarcely any space and is VERY handy to have on hand for troubleshooting.
