For the first point: entering deflections in the Traverse panel is simple. In the direction, instead of entering a full bearing, you can enter + or - followed by an angle, even in DMS.
+88-22-50
Keep in mind, this deflects off of the prolongation of the previous call, whereas these deflections are given as "lookback" angles, so you'll need adjust appropriately. You could enter -- in the direction field to get the 180 degree angle, then re-enter the field and deflect from there, though I've not actually tried that.
Second point: you got it, that's a delta angle. The Traverse panel should let you change the arc length column to a delta angle column so that you can directly enter the angle as it's written.
