Trying to sort out the deployment of T-238 using launched grenades as the delivery method.

I'm thinking...

Damage 4

Crit 6

Blast 4

Stun Damage

Concussive 1

Sound right? Or would Disorient be more appropriate?

I think Disorient makes more sense. You can still act while nauseous,* even if you're vomiting. If the gas forced you to violently vomit for long periods of time, I'd say that counts as Concussive, but it doesn't seem to be quite that strong from the Wookieepedia description.

* I just tried a Whopperito for lunch today and I'm still able to work, I do not recommend it.

Yeah, I'd say go with a few rounds of Disorient. As Atama said, it's possible to still act while feeling nauseous, but you're not going to be at your best while doing so.

Damage: 7

Crit: 4

Range: Short

Encum: 1

HP: 0

Stun damage

Blast 6

Disorient Quality 3

Potential special Rule: Follow up hits with that type of grenade lose the stun damage and reduce disorient quality to 1. Though not sure if I would go with adding special rules.

So, CS gas as opposed to CN-DM?
