If the vinegar (acetic acid) didn't get rid of the spots then it's either not hard water spots or you didn't apply the vinegar for long enough and/or at high enough concentration. Vinegar can be any where from 5-20%, use the strongest you can find. And the type of vinegar doesn't matter, it's the acetic acid concentration that counts - white is just easier to find.

NEVER use steel wool, or any other harsh abrasive, on glass. There are many mildly abrasive products available that are specifically designed for cleaning glass.

The reason the water is sticking is because of all the scratches you made when you used the steel wool. If you didn't use the proper materials and procedures to do the polishing, you may have made things worse.

Yes.
Get some good glass polish and make sure you use the proper equipment and procedures. If the scratches are deep enough, you'll never get them completely out
but you should be able to make them barely noticeable
.
Not that I know of.
