As for carrying the kit, two jackets come to mind:
1. SCOTTEVEST, specifically designed to carry lots of stuff, and
2. Massif Inferno jacket, designed in Nomex to carry a few important things and to protect the wearer from open flames.

I went with the Massif Inferno Jacket. It has enough pockets to carry the basics. Critical items go in specific pockets. The rest goes into the internal cargo pockets. The Scott eVest is a nice way to go if you need to carry a lot and need lots of pockets, but my memory wouldn't keep it all straight -- too many pockets for my taste.
