If i were you i would do what Inksoul has said, take out the storm raven. Putting interceptors in there is pointless because they move 12" normally, and they have personal teleporters that lets them hope 30" to where ever they want, so it gets rid of the need for the storm raven. You wouldn't be able to fit that much in there anyway!
With those spare points, I'd kit the Librarian with the Curiass of Sacrifice giving him
TDA,
FNP and It will not die. Smacking him in one of the terminator squads should cause a lot of hassle, with hammerhand being constantly cast ontop of other buffs. Putting him in the Terminators also means that he isnt wondering around on his lonesome, and means he is less likely to get picked off by high strength weapons!
You might also want to stick some more weapons on those dreadknighs, Heavy incinerators can cause alot of tears against blob armies, especially with 3 of them, torrent helps a lot as well!
Hope this helps dude
