Nested Return Flights

I am currently in Europe and have the following flight scheme:

Europe → USA (September)
USA → Europe (Christmas)
Europe → USA (January '15)
USA → Europe (July '15)

First, does it make a difference which combination of returns I book? (That is, (1+4), (2+3) versus (1+2), (3+4).) Say I would like to keep two flights open right now (3, 4) – is there anything I can do without paying the huge additional price of business class or similar?

Second, is there anything else I should think about? I'll try to book all four flights with the same frequent flyer program – any other hints?
