with what you have listed there i think it would be hard to diagnose and/or help you out without actually seeing the engine in person.

best bet would be to wait untill you pick the car up and maybe ask your questions then, if its running a zetec block it will have the dipstick at the front left of the engine (as you look at it) the engine size will be cast into the block roughly centre half way up.

if you are compitent on the tools though none of what you said is a major issue.
