Captain with the assault marines, reclusiarch and librarian with terminators or split off to provide some muscle to the other squads.

I prefer shooty terminators and I don't have a cyclone missile launcher as of yet.

Not sure what psychic powers to take with the librarian.

Tempted to drop something to buff up the sternguard, but not sure what to drop. Also tempted to go with vanilla honor guard instead of sanguinary guard

You're spreading yourself far too thin. Only one squad is not at minimum size! I would drop the allies completely and base the list around 2-3 Tactical squads with transports. That'll give you good flexibility and redundancy. If you want an Assault Squad as well then bring a Vanilla Marine one; there's no strong need for them to be scoring once you have the combat squad option.

The Dreads could use heavy flamers if they're going to be fielded alongside vehicles.
