Thanks. That makes sense - better sense would be not to take car to oil change place that doesn't put on filters tight enough or TOO tight.

The old one sure worked though. It was NASTY!

This is a good idea and I have seen it before. The only problem is these don't dry out like the factory onces so they will absorb water as well. You dont need the insulation so you can do without. Don't leave the lower engine cover off, it can cause other issues and you engine will then have no additional protection.
