understanding what 5.2 is going to do

Hello Im still new to wow, only playing for 9 months now (hooked, i love it) but im having trouble prepping for this next patch, my questions for you are simple I hope.

Should I upgrade my Honor PvP gear before the patch or just get an heirloom for my next toon?   Also is it worth upgrading my 483/489 gear or hold points for conversion?  

and can someone explain to me what is going to happen to my current pvp gear (warlock wearing 3 pieces of Malevolent/Conquest then the rest are Dreadful/Honor) I just dont want to blow all my points to find out i could have gotten something awesome post patch update, thank you for your time + answer in advanced

no idea how i got it like that^ Edited by MadMonk, Yesterday, 12:10 AM.
