As discussed just about a week ago, the HSE version implemented in QE is HSE06: http://www.democritos.it/pipermail/pw_forum/2011-May/020690.html
For changing the screening parameter, there is an input parameter called 'screening_parameter' in system (default=0.106). For changing the fraction of the exact exchange, use 'exx_fraction' also in system (default=0.25). I guess these are not documented anywhere in the official distribution...
