What job??

Your stats can go for either but I suggest going on to becoming a Sniper first and if you don't like it go Ninja.
I say go Sniper first because once you go ninja you cant go back (like once you go black you cant go back... >.>) to any other job besides Minstrel or Samurai (Special jobs)

I don't know much about Sniper gear let alone a Bow Ninja but you can refer to

Gear for Ninja:
If you decide to become a Ninja, the general gear to have -100% hp is:

Schwartz no up (preferably slot) -30%MaxHp, costs 1m-1.5m range
G.ring/Blue Ogre -30%Maxhp total with BlueOgre xtal, this costs around 4m
Magical ring ns -40% Max hp, if lvl is 200+ effect changes to adding +50%MaxHp 300-400k 

As you get closer to lvl 200 you'll want to save up or farm Ganei xtals 14-15m each
stats are: Atk+10% -30%MaxHp, if equipped in special equip MaxHp+30% (Cancels out -Hp effect)
3 Ganei is what most people save up for. 

The -100%Maxhp gear is needed for cloning 
when you become a ninja you learn a skill called 
Desperate move, small description:
a self only heal. When Max hp is at 10% or lower you will gain 2 clones after casting this skill
To clone just switch out one of your gears that doesn't put you at -100%hp and cast Desperate move.

Things to watch out for as a Ninja:
Your clones are your life savers! Majority of the time if you have -100%hp gear you will be at 1hp
the following are 
Poison (you have 1hp most of the time so yeahhh)
Stun (will remove all your clones)
Blind (make you vulnerable to attacks, clones wont be able to defend you)

Anyway good luck with Iruna and don't forget to have fun.
Sorry it's so long >.>
