If they have not changed the design, the retaining spring is part of the "extinguishing bar" (where you put cigarettes out) the clip tends to lock in the down position and needs to simply be pushed back up to engage the retainer in the dashboard opening

If you haven't changed the plugs or had the fuel system cleaned, now would be a good time to do it. The number 1 culprit for rough idles is dirty injectors or plugs. You can try an injector cleaner in a can (or bottle) for under $10 and see if it helps, and then work from there. If there isn't any improvement then if you are able to, check the plugs for any gunky buildup and if you find a bad plug, make sure you replace them all (or have them replaced) at the same time.

Probably have bad hood struts/shocks that hold it up. These can be obtained at the usual discount parts stores(Kragen,Autozone, Checker,etc) Usually just pop off on one end of a ball mount and unbolt the other after you have propped up hood. These shocks go bad from time or fluid leaks.
