Thanks for the advice guys!  Will let you know how it turns out. I am a bit concerned by the "bubbling" issue though. 
When I started the brew:
As the weather was cold, I threw the yeast in at about 31-32deg, then sealed it. I tested the airlock (press the sides) and the levels took 30 secs or so to equalise again.
Over the first night, moisture formed on inside of the lid, and the airlock was not level (meaning there was a slight pressure inside the fermenter), but I have never actually seen bubbles coming out. It stayed at 28 for the first day, then slowly dropped down to 16 over 3-4 days. The brown residue that Baz mentioned seems to be present.
I will do a taste/sg test tomorrow.
Jon - sounds like a GREAT idea!
Here are some pics of the German method.  Note - NO SUGAR!!!  Just (malted) Barley, hops, yeast, and water.  Looks like a fair bit more work, but would be interesting to try, at least once.

(If anyone needs a translation let me know)
But basically - STERILISE EVERYTHING - crush barley - mix with hot water (mash) - filter - do an "iodine test" (??? anyone???) - cook the mash/wort with the chosen hops - filter again - put in the fermenter and throw in the yeast.
