Got it all covered.
I carry upwards of $200 cash all the time and spare credit cards; not sure what you consider extra. I had an extra $50 in the car until I needed it so now I need to replace it.
Sunglasses fit in one of my many pockets in my left VOMP.
Spare key - I used to carry a spare set in my last backpack; and then the pack was stolen so...
I carry readers on my person at all times.
I have a pen & pencil in my VOMP.
I have painkillers in my EDC FAC, desk and at home.
I've got chargers all over the place (house, car, work and pack).
I've got water bottles/containers all over the place but only a collapsible container in my pack.
I usually carry a pair of leather gloves as well in a side pocket of the pack but I want to store some latex gloves in the pack as well (someone gave me a box of them, otherwise I would have chosen nitrile).
I typically have my rain jacket in the pack and I will be including my 2GoSystems Trifecta bivy as well.

Like I said, I have the EDC covered except when the unknown happened and my pack was stolen along with $1200 of gear. I've managed to replace everything except the spare car key; Ford wants an arm and a leg for that.
