If the tail seems ok pitch pump to check it still holds, then adjust the gain up until the tail starts to hunt-back of a few % and fly. Then fine tune as you see fit.
Once I get mine and its set up I'll let you know what I've learnt.
The "tail setup mode" turns of the gyro so it is easy to get the neutral position set. It also lets you move the tail pitch to the endpoints you select by moving the stick and then you confirm each direction with the set button.
