I did that mod when I put in my longtubes and highflow cat. I used the Dragon's Breath Performance one (supporting tuner). I was impressed with how sturdy it was built. It also cleans up the engine compartment.

Yup you can tear out the old pump and everything connected to it if you want, without throwing a code. Really cleans things up nicely. 1/2" pipe caps

The tube you speak of is the air tube to cat. I removed the cat and tube so I can't comment on how to cap it. If I remember correctly, it had a check valve just like the ones at the air tubes at exhaust manifold. If thats the case than a 1/2'' npt cap will work. You can remove the diverter valves and plug the vaccum line and tie up the electrical.
