Yes, with an image stabilization lens tripods are only necessary in rare instances.

No, regardless of using image stabilization lenses, there’s simply no substitute for the image quality you get by using a tripod

I would use both, as each has its purposes and one doesn’t necessarily cancel the use of the other.

Very important and I would make a purchasing decision based on the lens having this feature.

Not important. I prefer getting a lens with a faster maximum aperture at all focal lengths.

Does not apply because I have IS built into the camera body I own.

Yes, I still work with glass filters and always carry NDs and a polarizer.

No, I get all the special effects I need from software.

I am not sure what advantage ND or polarizer filters offer.

I just leave the camera on Auto White Balance because it does a fine job most of the time.

I use an Auto White Balance accessory and Custom set White Balance regularly.

I shoot all my images in Raw format and process for fine control of White Balance then.
