I recently removed existing linolium squares from my basement floor, only to find a black glue-like residue covering the concrete that is slightly tacky in spots. Do I need to remove it somehow, or can I paint right over it?

I would recommend removing that old gluey stuff no matter what you put on the floor. That black stuff is an old type of floor tile mastic. Bear in mind that if it is still tacky now after years of sitting under floor tiles, it will be tacky years from now, even if it is covered in paint. Your local paint store may have some products that will help you in the removal of the old floor mastic. Good Luck!
