Hey there!
So , first and foremost try not to give prices for every equipment in your units (2 much info as the Welcome/intro post suggests)
Now for the list :
IMHO you should Drop Karamazov , one space monkey (2 are enough) and the bolter Acolytes in the unit to add Coteaz (he 'll give you prescience for re-roll Note: you 'll reroll both gets hot and templates for the plasma cannons) and 4x Crusaders (they 'll tank the nasty shooting with their 3++)
I would add an
ADL with Icarus lascannon which Coteaz can man for
AA . This unit comes at 375 points provides really good shooting at 36 " and it's pretty durable at the same time .. You 'll have Coteaz who unlocks Henchmen as troop choice so you can take advantage of that by adding either one (or more) Deathcult Assassins x7 + Crusaders x4 + Techmarine combo unit(s) which is assault unit (put them in the SR or get a
LR) or more warrior acolytes in Razorbacks (take Assault cannon + psybolt or Lasscannon)
For me it's
DKs or Dreadnoughts in the list..but that's just me . I would recommend going Heavy Incinerator + Teleporter for the
DKs . The Dreadnoughts are more than OK like that. Same for the SR : it's OK but that's just me again ..
Hope I helped you a bit regarding what is considered "competitive" right now (I think

)
