T9 Question- SMN

[Lycia]

I've read mixed things about DoTs ticking on Nael during her jumping phases. Recently, I joined a PuG and was told by a Parser that I was pulling 340 with pet included. My questions for anyone willing to answer.

1.) Does the DoT's not tick? If so, then I probably should save my Contagion / RS casts for after jumps, which should probably raise my DPS drastically.

2.) Do I Enkindle at the start of the fight? By doing so, at the start will that allow it to be up during the Ghost phase?

3.) My tank was big about me not being in Melee range, and I was completely out of Potent Poison Potions, and was unable to run in for Miasma 2 (told not too) for my Contagion. Subtracting all those things plus my book hits, is that the main reason I was so low?

Be brutal if you have too, I have thick skin. My goal is to play the class to the best of my ability, and I feel with 110 gear, I should be in the 400 range easy on this fight.

Edit-
4.) How much DPS am I losing by using Mega over X-Pot of Intelligence? Due to my work schedule I'm close to broke, and have no time to craft.
