Ford Focus 1.6 Automatic X Reg - Various Issues?

Hi,

I have a few issues with my focus which have all started recently.

1 - Condensation on all windows (freezing in cold weather)

2 - High idle revs (sits around 2k mark for a bit) and goes down after driving.. if started driving before it drops when i slow down at a junction it has revved to 3/3.5k before settling again)

3 - Loud shuddering noise from passenger back end (near exhaust pipe) when starting engine up and when slowing down at junction with high revs (as above)

4 - The car is producing what I would call a little too much white smoke whilst driving and idle

5 - The central locking opens all doors but the drivers door meaning I have to reach over from the passenger side to open the drivers door from within

6 - Squeaky engine from cold start - constant high pitch squeak until the engine has warmed up

7 - Once parked up and out of the car, I can hear a ticking/tapping noise from near the drivers front wheel

Any help on the above questions would be greatly appreciated.

Thanks

David
