Simplify the admin end

First, once you assign users to the role of Author or Editor they will see quite a few fewer menu items (Settings and Appearance goes away) – see Roles and Capabilities. Try creating a second account for yourself and seeing if that helps.

You can then remove additional menu items using the Admin Menu Edtior which is a very well written and quite handy plugin.

If you need more control over roles than that, try the Role Scoper plugin.
