Post a photo of how things cut?
You are pocketing with a ball-nosed tool — better to do this with a perimeter pass (for the rounding) and a square tool for the balance.
The lines do show if you angle the preview a bit:
If you want a smooth bottom see:
Yes, if you only use roughing passes with an upcut which have a roughing clearance greater than the defect which they are likely to cause.
I use downcut on wood almost exclusively.
The only uses I make for an upcut in wood is if there is a roughing pass as described above (not very often), or if there are a bunch of tool changes, and if I can set up a final pocketing pass which cuts only the bottom of a pocket which was standing free as an island (usually only a pocket which had a surrounding …
Otherwise, to achieve what you seem to want you will need to leave the bottoms uncut, then nest a series of geometries to which you will assign a No-offset contour:
(adjusting the distance so as to arrive at an even distribution w/o a central point is left as an exercise for the reader)
