Newbie with cider brew questions

Hi folks,

Just doing my first home brew, decided to try a 'John Bull Cider' kit.

For the inital fermentation I put it all into a sterile brewing bucket using 'brewing sugar', left the lid loose and placed it into the airing

cupboard, nice and warm. After four days the 'foam head' had gone and using a hydrometer it was down to 1.000, sorry don't know the temperature, so I buttume it had completed its fermentation.

I bottled it into 2 litre PET bottles adding a couple of teaspoons of sugar along the way.

Now, a couple of days later I am seeing quite a bit of sediment settling out in the bottom of these bottles as they gradually clear and

wonder if I should have left it a bit longer before bottling?

With the last couple of bottles I had not realised that the siphon tube

had slipped to the bottom of the bucket so would have picked up some stuff from the bottom. Incidentally, these few bottles developed quite a 'head' when the sugar was added.

The main thing I want to ask is can I 'rack' them off again? Am I likely to loose too much 'fizz'? If so, what options do I have to add the fizz back? Could-should I add more sugar when 'racking' them off for the second time? How long should I leave it before racking them off?

For future reference..

. Did I bottle too soon? Should I have let it settle a bit longer in the bucket?

. Will the couple of bottles which picked up the bottom sediment need anything extra doing to them to prevent anything bad happening?

So many questions! Any advice greatfully appreciated.
