First one Tearing ...in a great hurry ..a tearing hurry
Anagram of great and in.. You are "finding " the answer in ....in + great .

These sort of clues are hard to define sometimes without seeing the actual grid .
Hundred lines for me !

4. Agree 'Dispense' . . . . When you discard something you dispense with it, e.g. 'I am going to dispense with this old car mat, I can do without it'
