Just like many already said, you really don't need that much redundancy. Keep it light and small, you do might actually have to carry it. The bigger the kit, the more likely it will be left behind.

The best way to find out what you need and don't need is very simple; test it! Any kit, should be portable(or at least have a part which is portable). Walk at least 15 miles with your kit and before you know it, you are tossing stuff out. Start practising with your equipment and practise your skills. Experience, knowledge, skills and will power, is far better and importent than having a reduncant piece of equipment.

and one thing, i spotted on the list: the lack of a stove of proper cooking equipment. If you going to carry that much, you might as well toss in a small stove and some light cookwear aswell.
