Hey Mechano and welcome to the forums.

Looks good to me with the chain rule and proper substitution but its been a while since I've done any vector calculus or line integrals, but based on the identities, the chain rule and the substitution looks good.

Hopefully we can get a few more clarifications here just to be sure.
