How i know i'm ready for an instance?

[Simos]

I have 2 hardlight items and waiting my 3rd before i go inside ifrit hard mode.
But if i'm correct i can offtank and do stuns, which would be easier for a new geared tank, correct?

Any. There isn't a really harsh check to tank Ifrit, Warriors do it all the time. Better geared means you are less prone to dying durring the nail phase, but generally ifrit doesn't hit hard enough any fresh pld can die with a decent party.

Being a stun bot doesn't require gear, just requires...skill. They don't care if you're just auto attacking, as long as you stun that erruption.

Again the only phase which better gear is remotely required is durring the astral phase, and if you have stone skin skill, and have your defensive buffs all ready, you can easily live through that part, and all is good.
