If the only thing that was done during the process is the spark plugs being changed, you are going to need to go over your work and look for anything that was skipped over.
Unplugged MAF, intake hose left off, unplugged throttle body, etc.

The oil in the plug tubes is from the tube seals leaking where the valve cover meets the tubes. This is a very common problem, however it will NOT prevent the engine from running. When the spark plugs are removed, the majority of the oil will run down into the cylinders. This will cause a brief stumble and some smoke on start up, but that is it.

If nothing else was done, something was either left unplugged or there is a massive intake leak (not too likely).
