So you have an Astropath and Officer of the Fleet to help you win at the reserves game, which is the name of the game with 7 to 9 Skimmers on the table. Plus Creed has his spiffy rules to aide this aspect of the game further. A good mix of special weapons should help you take on a variety of foes, and the number of Lascannon and melta's is adequate for Armour. The stormtroopers can gun through powered armour foes when they swamp them en masse, especially if they get softened up by the Valkyries. And even with the Elite nature of the Army, it still has a relatively high model count. 67-87 4+ armour saves aren't the easiest to power through. The key is to keep this army out of assault though. Hop around and shoot, mass your fire and eliminate entire enemy squads at once so you don't get assaulted and bogged down in the following turns.
How I'd run the list is in 2 distinct halves. First would be a standoff containment force. This consists of the plasma Stormtroopers, Sniper Vets and Plasma vets in the first Valkyrie Squadron. Deploy them in a line, ideally on an objective, and hold the enemy in with massed las fire and special weapons at a minimum of 12" range. Next is your assault force. This is the 2 Melta storm trooper squad and the flamer/shotgun vets. They sweep in from the side or middile in the second valkyrie squad and push horizontally through the enemy line, overwhelming them in short ranged fire fights, assaulting only when you know that you won't get bogged down or you will be assaulted anyways (might as well get the charge bonus). Try to only assault with the vets, as your storm troopers should always be shooting, that is where they excell the most. The last element in Creed in the Vendetta. While not a distinct part of either force, he lends more to the assault BUT in a very specific capacity. His squad should be hunting armour. They have the weapons for it and the vehicle for it and do not have the numbers to prosecute actions against infantry formations.
In the 2500 point list, the Melta vets should go with the assault force and the grenade vets with the standoff containment force.
