A 4' gaff and a hand gaff might be plenty. I use the hand gaff most and just slip it under the lower jaw without harming fish. I went to the hardware store and bought a 5' aluminum straight edge ruler and screwed it to the inside gunnal up against the transome. A quick easy way to measure as well as cheap and durable.
You might consider a hand held personal EPIRB with GPS. They run about $500 now on the internet. They do not float so don't drop them. You might consider the offshore type life jackets like mentioned above which have extra foatation and attach some whistles and lights.
A ditch bag is good to have with hand held flares, P-Eperb, handheld gps, your keys and wallet. Use a yellow SeaSeal/waterproof duffle bag type etc.
Just ask questions.....you'll probably over pack the boat and then start weeding out the stuff you don't need!
