[its all been said, I'll just add].... and don't worry overly about the PFL. Sure, its a tough one to get right every time... but the guy will be looking to see how safe you are within the bounds of others he's seen at the PPL level. I thought my PFL was not great... the examiner I had (God bless you Bob!) told me afterwards "I've never seen anyone do a good one really"!
Also, don't worry if you don't pass everything first time - there's no shame in re-sitting all or part of the test! Well, I would say that wouldn't I: my circuits were lousy on the day - my excuses relate to major x-wind and shear on the approach, but it was do-able... calmed down and did it great the following Saturday, albeit in better conditions.
Hope this helps, and good luck!
