1. Friedman p200 says that flexible exchange rates are 'a means of permitting each country to seek for monetary stability according to its own lights'. It is 'monetary stability', not any point on any tradeoff function that is under discussion there. That this must more or less mean price stability is apparent from the fact that later in the paragraph he says 'If all countries succeeded, the result would be a system of reasonably stable exchange rates...' That would clearly not be the case if they were choosing different points on Phillips curves.

2. Guy Routh, in Economica 1959 vol 26 issue 104, p304 uses the expression 'Phillips curve'. 

3. I think 'learnt about adaptive inflationary expectations from Phillips' means merely that Phillips may have suggested a particular formula for modelling expectations, rather than anything more profound. The idea that expectations of the future would change according to recent experience was hardly new to Friedman (or anyone else) in 1952.
