From personal experience as well as almost never seeing them taken: I'd avoid deploying Assault Terminators in anything other than an Assault Vehicle (which pretty much limits you to deploying them by Land Raiders or a
FW unit that's an Assault Vehicle). Instead, I'd probably make that a Regular Terminator Squad rather than a Terminator Assault Squad simply because Deep Striking a Terminator Squad (or deploying them via Drop Pod or another vehicle) is viable because they can shoot on the same turn the arrive by Deep Strike (or Drop Pod in this case), while Terminator Assault Squads have no ranged capabilities which means they are useless the turn they arrive by Deep Strike or disembark from a vehicle that isn't an Assault Vehicle. Also, foot slogging Terminator Assault Squads is dangerous - even if they all have Storm Shields - because they only have one wound.
TLDR? Replace the Terminator Assault Squad with a Terminator Squad so you can take ranged weapons.
Other than that, I reckon it's a fairly solid list, especially for a beginner's list at 1,000 points
