Are these going to replace breastfeeds? If so I would just pick the times you breastfed.
For bedtime we have always given a bottle after the bath, then clean her teeth and straight up to the bedroom for a story. The key thing is teeth cleaning afterwards, really. We've always done it right before bed so they have a big sleepy drink on their tummy to help them go to sleep. Our day-time milk has always been first thing in the morning, with breakfast an hour or so later. But selfishly that has always helped with getting DD through until she's at the childminder's!
At 10m we were definitely still giving any afternoon bottle too, before a nap.
Try and use beakers if you can, only because it's a pain getting them off bottles bitter experience
If you're using powdered formula then you might need to experiment a little with the times to get the water cool enough, but roughly it's boil the kettle, wait for it to cool down a little (we used to do half an hour, I think), then make the formula, then you'd need to wait again for it to cool down to the temperature your baby will drink it at. If you're doing the milk at the same time every day you should hopefully be able to slip into a routine of getting the drink ready roughly an hour or so before feeds, maybe?
A lot of people don't fully sterilize at this age. A good hot dishwasher wash should be fine for a drink that's being drunk very soon after making.
