Send the Bcash coins first. Cheaper fees, and they're the ones you want to move anyway.
I strongly disagree. Get the bitcoins disassociated and secure before messing around with the bcash (or any other altjunkairdropcoins).
Bcash does have some replay protection, and as long as you send the coins back to addresses you control, you can always import the private keys on the Core side if that somehow becomes necessary. Besides, if something goes wrong on the Core side and the coins can't be recovered (wrong address entered by accident or something), that's a tragedy. If Ver's crappy altcoins get burned, that would be a resaon to celebrate were usable fiat not involved.
