Ok, so I was able to get the nut off with a 2.5" basin wrench. (Thanks for the heads up on those being available in larger sizes!)

I went with the 3/8" OD stop valve and it worked perfectly. I did NOT use teflon tape, simply because it wasn't mentioned in the install manual and I didn't think of it until I finished, then came and read the post suggesting it. However, the gasket in the faucet-side line compresses a fair bit and should keep tension on the threads. Do I need to take it apart and tape it up, or will I be good?

Here's the new supply line setup:




Thanks for all the advice!
