In the solutions manual, the answer uses the equation -q(water) = q(ice). Is this because the ice is lowering the temperature of the water?

Yeah. The heat from the water is transferred to the ice.

The liquid water will lose heat and its temperature will decrease, and the ice will absorb that heat and melt/temperature will increase. This is why the q(water) is negative and q(ice) is positive.

Yes, in thermodynamics we must remember that energy is conserved and that qsys + qsurr = 0, and thus qsys = -qsurr; the system being the ice and the surroundings being the water.

Yes because there is a transfer of heat from the water to the ice
