Looking to dive into Khador, need advice.

Add Vlad2 to your list of caster, he's a popular choice here too.
For your jacks I think two kodiaks is enough, I run Sorscha3 with 2 kodiaks and a maraudeur and it's ok like that, the threat of siege weapon with flank is interesting to have in the list. 
Ruin is essential if you run Butcher, but Beast09 is not an auto include with Sorscha, I would list him as not a priority.
Behemoth can't be taken in armored corps, no need to bother with him.

I'm in the camp chariots are meh, one is nice to have as an extra but you really don't need one, they are super specialised piece of tech that are very hit or miss.

You'll want two of each tanker though, most list run 4 tankers and if point are really tight they will run 3. Two is not enough, the tankers are the workhorse of most armored corps list.
One kovnik and one drakhun is enough, I like at least one drakhun in my Sorscha3 list.

One unit of bombardier is good, two is too much, if you want to bouble up on one of the units it should be shocktroopers, they are the best man o war unit in the theme.
Only one unit of eliminator is necessary, they take up your merc slot so you will never be able to run two units in armored corps anyway.
Two min battle mechaniks is good, you'll always be running min units so no need to bother for more or for the CA.

This is a good start. I do think you can make an argument for 2 units of each of the core - in part because it lets you really explore the variations in the theme - PP's best in my opinion for this reason.....and I also think 2 Kovniks are important because, again, you could play for YEARS with the theme and not exhaust things.

Want to brick and throw ARM in face - 2 Shocks with Strakov2 hot swapping QUicken and IR between the 2 units
Want to shoot and laugh - 2 bombers wiht Butcher 1 and 2 Spriggens.
Want to play jank which is Very Very good - 2 demo corp, 4 tankers and Zerkova1

If you go this route you can actually wait on the Drakhun, behemoth (see above) and expand your jacks more slowly.

I strongly encourage you to magnetize both the Kodiak/Grolar kit and the Juggernaut kit.

Grolars are pretty fantastic, though it seems as if most people never see beyond the PC 18.

Likewise, you might find that Decimators are pretty solid (despite, again, most people dismissing them), and Destroyers and Marauders have their uses. The Juggernaut is... well, it really needed to stay PC 12. It’s pretty no-frills for 13 points.

Lets be honest with ourselves, in a game with a CID system where the rules for various models can change and the meta shifts with releases learning to magnetize all your jacks is going to be the greatest possible skill you can develop in this game if you're looking to save a buck.

The Grolar is a brilliant piece of kit. It's the only non-character jack we have that outdamages the Juggernaut on average due to the auto KD and loads of initials. But expensive jacks are not the 'in' thing at the moment, alas. I stick them in a fair amount of infantry-heavy lists, though.

I don't really run a Decimator outside of Sorscha1. It's a poor melee option for the cost, and whilst the gun is damn high-damage the accuracy lets it down hard. I always feel it needs more focus than I can ever spare. I'm tempted to try marshalling it on a Forge Seer as Strike True! and Take Aim! could both help it, but thus far I've not found the time.

AC doesn’t need big B. You get mini feated HoF Bombideres.  12 big blasts.
