I should the whole mail....sorry about that. How about this: get a uC board (e.g. STM32discovery), replace the crystal with a 10MHz input from your frequency reference. Use the on-chip 12bit (really just 6bit) ADC to sample the sine wave from your mains. Do phasor measurement in software. Probably any sampling frequency between 200Hz and 1kHz should do the job, Which is slow enough so you can still handle the samples with the uC alone and don't need any fancy DSP.
