You did good, no rocket science!
1 OBD2 in its native mode supports one device. 2 You can always drive a bit to warm your transmission quicker. 3 I always put bit more WS fluid in than I empty out for that reason, you want small steady trickle with no breaks, better to have touch more than not enough. 4. I would add fluid and let car sit for a while before checking it again, fluid would circulate as you warm up, 1/2 q is good amount to add in case your drip is slow.
