How best to cube weapons, and scroll armor

Hi everyone, I think I need some help with two things.

1) What stats to cube for on my weapons (all legendary) with violet cubes?
Without potentials from my weapon, secondary, and emblem, I have 161% boss, 0% attack and 86% PDR. My weapon and secondaries have crap pots, but my emblem right now has 40% PDR, 30% PDR, and 9% str which will bring me up to 94% PDR. Weapon and secondary will definitely cube over, but not sure if emblem is worth keeping. I do have a few other options for a bit more PDR I'm just shy of an optimal number.

2) What to do with my currently half scrolled RA armor?
Here are the images of them: http://imgur.com/IEz4Vgo&mNzLHpt&ABlM2nR#0
I scrolled them before spell traces came out, so now I don't know how to finish them. Should I innocence them and 30% spell trace? Or clean slate and 30% spell trace them? Or clean slate and use CoGs?

Thanks for your help~
