The cost of your sorcerer is off. It should be 135 for a Level 3 mastery and sigil of corruption, unless you meant a Level 2 mastery, in which case, you are correct on the point cost.
At 1000 points, I suggest that you drop one mastery level and the sigil to take Terminator Armor and
MoN. This puts you at 125 points. Because of the
MoN, you stick him with the
MoN CSM.
With the
MoN, you have a T5
HQ that has good survivability in challenges, which must be accepted. You get a 2+ armor save, which will probably come into use more than your 4+ invuln would have and you still have a 5+ invuln to fall back on, and you won't lose your armor save to a power sword or maul, which the T5 gives you a chance against.
If you have it really hard for the Biomancy powers, you can add another Mastery Level for an extra 25 bring your point cost for the
HQ to 150. At 1000 points, two powers will be pretty strong and at higher points games, the 3rd level would be a given, especially for the cost of it.
I'd suggest your
MoN CSM lead the charge. Their T5 will make them more survivable than your
MoK guys.
Of course, just my opinion and how I'd play it in your situation.

CCW are free if you give up your bolter or 2 points per model otherwise.
On a side note you may want to change the icons as the mark specific sort of ones are generally better I think. (wrath etc)
Icon of Vengeance provides fearless. Icon of Nurgle provides Fear, which is rendered useless against Space Marine Chapters, as they have
ATSKNF. Changing to the
MoK might be nice for the Furious Charge and the charge reroll.
Also, keep in mind that Icons add 1 to your assault results. If I understand that correctly, it means that your Icon bearing units win any assaults that are tied. Can be pretty nice. Of course, your Icon bearers are going to get targeted by characters with Precision Shots/Hits.
