I'd say on the paper you give your friend you might also want to list some of the most likely major symptoms you might get. This is especially true if you might have a symptom that most people would go to the ER for, but you wouldn't. For example, a friend of mine with CFS/ME occasionally ends up on the ground in pain/fatigue and unable to speak because of the pain/fatigue. For her, she needs to just have a few minutes to rest, but if it was someone other than her (even many people with her same diagnosis) that's something that would mean go to the hospital. She's had a lot of problems with people calling ambulances for her in public places when she knows that she doesn't need to go to the ER and there's nothing they could do for her.
As well, while EMS staff are generally well trained, they're not going to know every diagnosis out there and so many diagnoses have variable symptoms knowing specifically how it effects you is just good extra information.
The only other thing I can think of (not knowing your medical history) is that if you have specific specialists, it'd be useful to have their numbers written somewhere so that in case of an emergency, the hospital in FL could call them. (Keeping them in your cell phone also works as long as your cell phone can be accessed by someone other than you in an emergency, not so useful if you have a password on it)
