Hi, welcome to Dakka! A couple of things.
Drop the 'Eavy Armour, it gets cancelled out too often to make it useful and isn't reliable enough. Take a Cybork Body instead, at least it can't be cancelled out.
I'd take the Big Mek with Kustom Force Field instead. The only time I'd recommend taking a Warphead over him is if you were running a couple of Dakkajets, which you're not.

As much as it pains me to say this (I ran 3 squads of 10 Nobz in Trukks through 5th) I'd drop 3 Big Choppa Nobz, and take 1 more Power Klaw Nob. Also, with that Trukk is going to get blown away given the size of the threat of the unit inside, take a Battlewagon with a Deffrolla,
RPJ and a Big shoota instead. Also, drop the 'Eavy Armour, take Cybork Bodies. Also, your Nobz are a Troops choice because you're taking a Warboss, not an elites.

I'd probably drop both of these, you already have 3 troops choices at 1,500pts, more is a little overkill, and these points are better spent elsewhere.
More trimming, you've almost got it with the second one. if you're going to take Deffkoptas, take them as individuals with Buzzsaws, so that you can fly them up first turn and punch a vehicle in the face. Drop these, and take 2 squads of 1 with Buzzsaws.
Drop this too. I know the boomgun is tempting but that's over 100pts, for a vehicle that's not very durable and not very reliable.
Then spend your spare points on Lootas.
Hope this is useful.
