They look great to me! I've got a 4 lb pot and I use a Lyman bottom pour lead dipper. It's been a good combination for me.
You will probably need something else to calibrate that NOE thermometer. On the I have, the dial spins very easily and got out of calibration before I could even use it. I finally got it calibrated using a PID controller, then put a lot of superglue on the back of the spinning dial piece to lock it down. I would not recommend that thermometer.
I use the sinking boat method to fill my bottom pour ladle, turn it so the sprue nozzle is aiming down into the pot and let it fill through the little hole.
