Dragoons: A Rotation Reborn

[ProphetMagnus]

Weapon Damage: 8.732
Strength: 1
Determination: .325
Crit: 0.204
Skill Speed: .178

I would love some help with this information as I'm very new to raiding and min/maxing. I've just beaten t5 with my FC and we're working on t6+ from now. I was hoping I could get some questions answered by the Dragoon Community:
1 - With weapon damage (WD) being the best stat - and reading what it says about the stat weights - if I lose 8< Strength but gain 1 WD then it's better to do the swap? I guess I'm asking if the highest possible WD spear I have should always be a priority to equip (at this stage it's the Allagan Spear).
2 - I'm focussing my build on DET>CRIT, but I've been told by other Dragoons in my LS (in other raid parties) that I'm doing it wrong by doing this. Basically I work my choices in this order: ACC (Cap)>STR>DET>CRIt>SS. Am I doing it right or do I need to go back to the drawing board? (I get that in some cases I'd have to sacrifice some points in STR/DET/CRIT for some reason but that's basically how I plan my gear).
3 - With my limited grasp on WD, and it's place in stats, is this the way I should plan my gear from now on: WD>ACC(Cap)>STR>DET>CRIT>SS?

http://eu.finalfantasyxiv.com/lodest...racter/269046/ This is my character profile (hoping it updates soon but if not I've equipped the Allagan Spear and Hero's Bracelet of Slaying). For my crafted gear I'm planning on maxing the ACC DET CRIT in that order (I've seen a few examples in this thread so I might look at those more for guidance)

Thanks in advance for your help!
