@SippingSipsmith Welcome! Sparklepup was the same with eating stones so we used to take him out on a lead. Is there a place in your garden without stones that you could designate as his toilet? We used to try and get every stone and then realised he was just doing it for attention so we just ignored it and now he doesn't bother. If he does pick up a stone he will just chuck it around a play with it, pounce on it and roll around with it which is very funny to watch.
We didn't get him til 14 weeks but he fell into a routine fairly quickly and it hasn't really changed:
6 - wake up, breakfast, toilet, walk
7 - back to bed
10 - wake up, play, try to do some training and fail miserably so play some more.
11 - bed
12 - wake up, lunch, toilet, walk
1.30 - bed
3.30 - get woken up by kids coming home from school, play, try doing some training and fail, play some more
4.30 - bed
5.30 - wake up, dinner, toilet, settle with a chew
7 - bed
9 - wake up, chew, try to convince us to play while we try to convince him to settle, last toilet at some point usually 9.30ish
10 - bed
Hope that helps! It does get easier
