Wow, first let me say you have some great stuff for cast time. Achieving instant cast is ideal because then you no longer have to wear the flimsy-as-paper orleans gown to prevent being interrupted, and can then substitute for a better armor with more def, I like valky armor but I'm sure there are more efficient pieces out there.
You might as well try to get to instant cast, and you're already almost there; -32% from rwcs, -30 from faw and another 20 from CoD puts you at -80%, a katherine keyron card in your Cod would get you to 89%, if you were lucky enough to +10 your CoD, that means 90% total with the kk card. For the remaining 10%, you could use temporal boots with spell 5 enchant, but this is costly and/or time consuming, so it's up to you.
For temporal boots, I use +6 temporal STR boots with spell 4, since I havent got enough coag spells to up it to spell 5. The reason i use STR boots is the small atk boost can make the difference between 3 shotting and 4 shotting a mob. However since your cast time is already fast enough, i think sticking with your dex Ea 4 boots is fine for you. I dont have FAW so I need all the extra cast time i can get
About the stats, it seems fine to me what you have in mind, but my gene is built around +9 hbp bonuses to increase CC and AB dmg, but what you have here is better, i think, considering the faw. However i would maybe go for a bit more vit, my gene right now has around 70 vit and feels a little too squishy.
For the weapon, the weapon I've found that does the most all around damage for me is +9 red twin edge with 3x archer skel, no other weapon I tried worked as well for me, and while the fire element seems like it would be a problem, enemies that are resistant to fire can be bypassed using elemental converters or sorcerer endows, so keep that in mind.
About leveling, if you dont want to do TI and watch rangers have all the fun, i hung out in nogg road from 100~110, then moved to naga/cornus/dark pinguicula in new world from 110~125 and have been in scaraba dungeon 1 until I felt confident enough to move to scaraba dungeon 2.
Mainly you are doing fine for leveling, you have some top-tier cast reduction gear and the only thing I would really change is the erde to a RTE. Good luck!
