I've successfully overhauled the rear hub. It rides smoothly now and hopefully the occasional "thunk" that happens while pedaling doesn't come back.
One more thing though, have a look at
my freewheel and tell me if it's badly worn. I reckon the thing has done about 1000 km.
I realise that my freewheel is bottom end stuff, as I can find it for about £7 new. Would it be good to replace it? I don't really have any trouble with it or my derailleur at the moment.
I do want slightly lower gears, as I never use the 28T and 24T cogs; however it seems that just about all 6 speed freewheels start from 14T. I've found some exceptions though.

Are used freewheels a good idea?
