They are not dumb questions. Moreover, everyone here has been in your situation once.
As martyntdci have stated, it's to personal preferences what oil/part to choose. Sadly, the leading reason for people in most of the cases to choose semi-synthetic oil is the lower price. But you can be sure that you need fully synthetic oil for your car.
Ford recommends coolant change to be made at every 10 years, so don't bother with it.
P.S. The list from hinggsy is very good if you don't bother to stick with OEM parts.
Personally even though ford says 10 years its just something I would do sooner. But it is completely personal preference what you do.
I maintain our family of 4 cars and always do extra when servicing doesn't cost much extra and is cheaper than a basic service from a dealer its just something I do.
its from when the plugs were last checked dust and debris gets into the area around the plug hole i try to clear it out with compressed air first garages dont so when you copper grease the threads and try to put them back in the grease picks up the dust and crud and it gets caught in the threads
explains it as there pretty concealed in the focus so a perfect trap for debris/dust, didn't think of that, was wondering why it didn't look more of a copper colour on the pictures.
I wouldn't mess about with it and take it straight back to the dealer without hesitation unless you have caused the damaged I would let them fix it at the end of the day it is a new car and that is what the warranty is for.
bosch are standard in ford focus from 2004-2007 and many mk1 had no issues with them ever on any car ive had no issues with the ngks either so really its a toss between the two its a bosch coil pack and bosch leads they are single electrode the focus doesnt like the 4 electrode ones and bosch dont even recommend them i use the iridium ones with no issues
Any iridium's from the main makers will be fine, I have probably over complicated it but to be blunt if you can afford iridium's get a set may it be Bosch, NGK or Denso if not I would personally get a set of NGK's.
I thought about the 4 electrode ones but it was the ones I got told to get by my Ford main dealer when I went to buy my belts not a clue why there are 4 electrodes as the spark will choose the path of least resistance and the other 3 electrodes will just get a carbon build up.
at a guess from experience with other cars if you use the key to lock the car instead of the fob it wont activate the alarm, may be different in a focus but that's how it has worked in other cars I have used.

thanks for the advice guys' have talked to my fitter again he is happy to take another look at it (know the lad well) since my last post fluid level has not changed' so maybe all is ok' unsure at this point' I will get to the bottom of this issue though' all parts were from ford and all belts changed at the same time
If its not going down now it could be that there was some air left in the system, that has now bled out.
