I don't see where those grunge guards are going to do anything positive. Well, ok maybe they will make you feel better so that might be one thing.
First of all it appears that you are preparing for some VERY extreme winter conditions. Keep in mind that if you are going to run a derailleur in deep snow, those grunge guards are not going to help your drive train, which will be your primary problem.
YOur pulleys are still going to be exposed and so will your chain/cassette/rings. On top of that, the rubber boots seem like they would trap moisture and snow and not allow it to fall off or to dry as it should. The rubber also might get very hard in cold condtions and impair your derailleurs.
You simply don't need those gadgets.
The mits seem like they would be ok but many people ride in many very cold conditions very comfortably with standard gloves/mittens. Those mits look very cumbersome!
These are just my observations after riding daily through two Kansas winters. YOu can take my advice or leave it.
