Engine rough idle. Rocker/Valve cover gasket? Options

[thedrunkfish]

After my last service the mechanic told me i should look at getting the rocker cover gasket replaced as it was leaking a little. After changing my spark plugs recently i noticed some oil leaking onto the spark plugs wich would be a direct result of this leaking.
Also recently the engine has been idling roughly, the car shakes a little but doesnt stall, it's noticeable from inside the car. Also the engine seems to hesitate under acceleration but gets better as the engine warms up.
Could this oil on the spark plugs cause the rough idle or is it something else?

Damn now i feel dumb. There is a little story to this one. I decided to check my spark plugs today to see if they had too much oil on them. Plug 1 came out fine but plug 2 weeeeeeeeell, plug 2 had snapped off at the bottom of the white bit of the spark plug, no idea what it's called. From then on it was damn near impossible to remove with my socket set, tried everything. It was obviously loose in there but couldnt get a grip on it. I was firing up the car to drive it to the mechanic and low and behold the pressure spat it out. Replaced spark plug and no longer have a rough idle!
