Hello.  Thanks for your question and the really good photographs.  It looks to me like peach leaf curl.  This is very common in our area, and sometimes difficult to deal with.  Managing diseases and insects in home orchards is an Oregon State University publication that provides recommendations.  http://ir.library.oregonstate.edu/xmlui/bitstream/handle/1957/18027/ec631.pdf;jsessionid=82C69E14F3D...  Unfortunately, treatment begins with winter sprays, often 3 or 4 spaced throughout the winter.  There is no reason to treat it now, but in the fall, make sure you rake up all of the leaves and destroy them (not composted) and follow the schedule.  You may have better luck next year.  You may even get some peaches this year, so stay tuned and good luck.  Linda
