Question surrounding trinkets

[Fluxhollow 0]

Greetings fellow warlocks and theorycrafters, I need your help with something

 

I recently got the Naraxas Spiked Tongue trinket (840), but I'm not sure its an upgrade. 

 

Heres a link to my armory: http://eu.battle.net/wow/en/character/magtheridon/Fluxhollow/advanced

Here's a link to the items I'm considering:

http://www.wowhead.com/item=137349/naraxas-spiked-tongue&bonus=1727 (Only does 158,261 proc damage on live it seems)

http://www.wowhead.com/item=134292/nightborne-researchers-phial&bonus=1826 (1073 Int, 882 haste)

 

Equipping the tongue would drop me ~2% haste, and I'm already sub-30% so I'm not sure if it would be an upgrade.

Which also brings me to my next point. What would be the best way for me to calculate if a trinket with a proc or use effect is an upgrade over raw stats?

Additionally, as you can see on my armory page I have most of the class hall set equipped, and I do have access to the 8-set bonus aswell.

How would be the best way to judge wether going for the 8-set bonus is a dps increase? Similarly, how would I judge whether or not dropping the 6-set bonus is the right move? 

 

 

Any help or feedback would be very welcome.
