MateO,
Doesn't look like anyone answered the one way valve bit of your question...
This confuses me even more because i dont see how (after turning off the gas) the regulator is meant to show the pressure reduction in the keg if the one way valve does not allow any CO2 (and therefore pressure difference) to pass from the keg to the regulator.
So... This part is pretty simple. As the Co2 is "absorbed" by the flat beer the pressure in the keg reduces = low pressure... the pressure on the other (reg) side of the one way valve is higher = high pressure... The one way valve allows the high pressure Co2 (on the reg side) to flow to the low pressure situation inside the keg. Hence the pressure reg will display the real pressure inside the keg
Only time this won't be the case is if you over carb and then shake or warm up the keg - thus releasing Co2 from suspension - which can't get back passed the one way valve to the reg. But if you have that happening then... you have just saved yourself a very expensive trip to your HBS for a new reg, which is the reason I have a one way valve.
I do have a question to add though! (maybe Butters can help?) Does the 'slipper method' produce the same fine sticky head that the "sit 'n' wait for a week at pouring pressure" produces? ie is it the pressure or the time that makes the difference?
I currently use the Ross method amended to 250 Kpa for 2 - 2.5mins - turns out ok.

dito warren. I find just chucking it into the keg fridge for 1 week on 15psi does the job just right with out needing to overly man handle the keg.
edit v2: re gas leaks, if you fail to check regularly with soapy water or similiar, then you're just doing bad practice.....I check all my seals, joints etc at least weekly. It's just common sense.....2c
