Sorry for not getting back but I just saw there was a reply.
If what you have set is working, I can't suggest any futher changes. As you may know I am not a fan of the spiders and monkeys gadgets. I deem them unnecessary. You can not get every color to match no matter how much hair you pull out. You can get one or two and I suppose the gadgets work for that. For general work they are a waste of money, IMHO.
Light and dyes are not the same thing.
I am not surpised you are seeing a slight reddish cast in certain colors. Canon printers seem to all have this bias. As far as I know there isn't anything you can do about it. Except fix it in PS or LR. Also, IMHO. it makes skin tones very nice. But every picture is not of a face or body. Try adding a little blue filter in PS and see if it helps.
