Awesome! My friend and I simul-rapped the bridge itself this spring.
Years ago a relative had a car that came with super grippy gloves (for changing the tires, maybe?). Kinda wish I still had those.
Edit: They were kinda like these: https://www.amazon.com/dp/B005QHQ1AA/ref=cm_sw_r_cp_api_glt_fabc_FK39Q3AFXFX4Z2TXF76J
I've tried quite a few waterproof cases and didn't like any of them. Plus most phones are water resistant. I have an OtterBox Defender + glass screen protector on mine which works well. Instead, for dry canyons I attach a little pouch to my pack like this one: Backpack Pouch or use a little silicon lanyard to keep it handy when I'm in stemming canyons. For wet... well, I'm still looking for a good solution for that besides throwing it in my canyon keg! If you find one that lasts more than a few canyons and can get good quality photos lmk!
There are times in caving when you might pull rope through. On a couple occasions we've used a method involving two figure 8 descenders on ends of a webbing anchor. Rope goes through small loop of left 8 and large loop of right 8. Carabiner on a bite keeps static rope from pulling through left 8. Rap down static rope on right. To retrieve, pull Paracord attached on left of carabiner lock. Static rope pulls through 8s. At the end of the static is an overhand just small enough to pass through large 8, but big enough to catch small 8 and pull the whole anchor down. If anything gets stuck, you're screwed.... But personally, I sure as hell wouldn't trust a fiddlestick on a 600' drop ^description to help you find this type of anchor in reference material. Take the details with a grain of salt please.
Disclaimer: When it's your life, please don't trust advice on Reddit, especially mine :) do good research from time-tested references. And shell out the $$ for the right equipment once you've done the research. Dying is cheap, staying alive is expensive.
On Rope is a widely used reference book for static rope techniques used in caving. May give you some insights. https://www.amazon.com/dp/1879961059/ref=cm_sw_r_apan_glt_fabc_W1Y03XE1PXZXAD8E5BBB
Post pics when you do it! And have a blast!
ah, didn't see the emergency blanket was on there. improvising a tourniquet is not a bad idea but considering you can apply a cat-5 one handed, I would just pick one up anyways. you can get Halo Seals pretty cheap, they're thin and light as well. those are just in case something rare happens but considering they're so small, light, and cheap it can't hurt to have one. mountain lion, bear, and wolf attacks could all cause a sucking chest wound. or like i said falling on a stick, you never know. better safe than sorry in my book.
As far as I know there's no guidebook in English for this region apart from this one which lists a few easy trips in the area.
But since canyoning in southern France is very popular there are usually information boards at the top of each canyon with a complete Topo, marked emergency exits and all kinds of other informations. Go to descente-canyon.com look at the map and filter for the highest rated canyons to get an idea where to go.

Recommend this in Zion: Canyoneering basic class - Zion Adventure Company
You can also rent wet suits from them.
I don't know about Bluejohn, but I was in same situation: climbing experience but no canyoneering experience and my son and I had a really good time with Birch Hollow and Subway. For Subway we paid somebody to drive us to the start. You can get references for stuff like that at ZAC.
Note that you need to pick up permits for the Zion canyons.
I recommend this book: https://www.amazon.com/Zion-Canyoneering-Tom-Jones/dp/0978961404/ref=sr_1_1?ie=UTF8&qid=1487181084&sr=8-1&keywords=canyoneering+zion
And if you're doing this all by yourself, you have a really long static line?
