>>32630717If you breed those two (and considering you don't have the Shiny Charm), I'm pretty sure the odds are 1/1024 and no, the non-Ditto parent's gender doesn't matter. And about SOS vs. MM, it depends. If you're just looking for a trophy Shiny or anything like that it's the better method, but if you want one with nice IVs, guaranteed nature etc, go for Masuda Method (egg hatching).
