1. Windows task bar visability is part of design. Without it you can't start new Windows application when in Coherence. Optionally you can switch it off or autoplace it - check Coherence tab in Parallels Tools Center. 2. "Isn't quite right resolution" is also part of design. Coherence working area is exluded DockBar and Mac menu. 3. As to artifacts of Windows desktop on fast windows moving - they are in this beta and work on it's improvement. One of workarounds - you could set in Windows blue wallpaper and artefacts become hardly visible.
