From what I can tell, the above ship classes are:
Venator-Class Star Cruiser/Destroyer. There's only one here, and she's located in the very back. Hard to miss.
Dreadnought-Class Dreadnought. There are a few of them scattered around. My count is three.
Executor-Class Super Star Destroyer. The big bad boy in the middle there. Very hard to miss.
Victory-II Class Frigate. Not to be confused with the Victory-II Class Star Destroyer/Cruiser, which is not present. There are five Victory-IIs in the picture.
Immobilizer-418 Class Interdictor Cruiser. The ships with the Gravity Well Generators. They could also be Enforcer-Class Picket Cruisers, which share the same hull.
Tector-Class Star Destroyer. May very well be an Imperial-II, but we never get to see the presence or lack of a ventral hangar, so this one is a fifty-fifty. It is most certainly not an Imperial-I Star Destroyer, as the bridge control tower superstructure is less obtrusive than the X-shaped design seen on the Imperial-I.
Assertor-Class Super Star Destroyer. This one was hard to identify, but the profile seems to be that of the Assertor-Class. An alternative would be either the Mandator-Class (which is hard to find visual models of that are consistent, so I think perhaps not), or the Bellator-Class. However, the ship shown here has absolutely the wrong engine configuration to be the Bellator-Class, so I'm happy hedging my bets on the Assertor-Class.
As for the planets...
It's Abregado-dai, a volcanic moonless planet which orbits close to the star Anza in the Abregado system. Mustafar would both be too easy, and occupy the wrong orbital position, as Mustafar is the third planet orbiting it's star. Abregado-dai is the first, and is moonless, which fits the image here perfectly.
And the bonus image is of Coruscant. Brilliant work guys, looking forward to your eventual release!
