Engine Problem!, Want to see wat you guys might think it is Options

Ok. My Celica's leaking a little bit of oil. I checked the engine and found a small leak out the back from between the head and the valve cover. So far ppl have said its the head gasket. The engine also sounds rough at idle. And when its cold (which it doesn't get very cold here in Houston), the engine goes up to 2000 rpm and sounds weird. I'm pretty sure it is the head gasket but also figured i'd try to see if someone could give me their opinion. Another prob is that i'm not sure if it would be only the head gasket. haha i tried to explain the problem as best as i could. So...any suggestions?

If it turns out it's as simple as the valve cover gasket, IMHO you're best off getting the whole gasket kit that includes the o-ring gaskets for where the spark plug holes are and the PVC valve grommet thingie (if you have that on a GT, not sure about that). You'll also want some high temp silicone gasket maker stuff to seal up the curvy parts and around the (damn, I can't remember what it's called) whatever it's called near the cams, facing the timing belt cover. It's a metal half-moon shaped thing.
