What I personally do:
1) I just slosh them in a freezer bag filled with 10% bleach solution as you've stated. Then LET THEM AIR DRY a few hours. Lightly seal any exposed cut ends with pruning sealant and let that dry.
2) Wrap each cutting individually and as tightly as possible with self clinging plastic wrap, leave no space for air. Place in a freezer bag and leave them in the fridge.
I don't know about specific temps but as long as your fridge is working and it's "cold" in there, you'll be fine. Cuttings can be stored for several months, I would plan on using them within a year though.
