For the Attack/Armor upgrades, did you try both kinds? In the campaign there are two kinds of lvl 1, lvl 2, lvl 3 upgrades. This is because there's an option to get Armor upgrades that also upgrade health, and attack upgrades that also increase attack speed. For instance right now I'm looking at terran weapons and there is Terran Infantry Weapons Lvl 1, and Terran Infantry Weapons Ultra-Capacitors Lvl 1.
For the Raven, you could try Allow/Disallow ability for player, and choose Starport - Build Raven ability.
