Rick,
I only just found this thread and can see all your questions have been answered. I too came to the XS10 recently after using Pentax SLRs since 1969, and of course Pentax DSLRs later. Really just welcoming you here. I set my XS10 similar to yourself except I do prefer the lens aperture ring. I still can't get used to having to switch the camera on before focusing and zooming, when with DSLR I very often did that first, before deciding whether the shot would be worth taking. That habit probably came from starting with film SLRs.
I tried both XT4 and XS10 before buying and much preferred the latter's handling, my only concern being its lack of weather sealing, because that was always a Pentax feature I found I could trust.
Cheers, Simon
