Yes, the TPA (Transient Program Area) did indeed start at 0x100 MS-DOS did as well actually, unless they changed it later. One feature of CP/M I liked were the user areas. Officially there were only 16 but if you knew how you could find all 32. So, in drive C: you actually had 32 'levels' you could put stuff on. If I remember correctly they'd all run from level 0 too, so you could hide EXEs from the casual snoopers. <g>
Best,
