Chaos Lords are not bad. Just not optimum. If you take a Lord run him with Twin Lightning Claws, and either a Mark of Khorne (for general troop killing) or of Slaanesh (for Initiative 6 character munching). That's all he needs. Never a Daemon Weapon.
No you haven't been thinking about tactics

. Any army that can kite well (mech. Tau, Eldar) will just run loops around you. If you are playing in a casual setting your opponent will either be able to deal with you, or not and will get ripped to shreds. For me that's not that fun really. Rock, paper, scissors.
I assume you take rhinos for the 'Zerkers because without them the planned list adds up to 1425.
Really to make games more balanced I'd take 3 troop choices in lieu of the 10 Man Termie squad. Mount the 'Zerkers all in Rhinos. And then give the Lord's squad a Raider (having sorted the equipment) - or get another 5 man Termie squad to deepstrike if you're set on using that many.
The Article Regwon suggests is a great one covering everything you need for the Terminators. The only thing I would add is in a multi-purpose squad (using IofCG) I (if I used Terminators in a list) would probably make one Terminator a Champ. - the one with TLC (if I had the points). And that's just a personal preference.
