The option MeshRange will set the range:
ListPlot3D[Table[Sin[x*y] + Random[Real, {-0.15, 0.15}],
{x, 0, (3*Pi)/2, Pi/15}, {y, 0, (3*Pi)/2, Pi/15}],
MeshRange -> {{0, (3*Pi)/2}, {0, (3*Pi)/2}}];
The option Ticks can then be used to specify the ticks
ListPlot3D[Table[Sin[x*y] + Random[Real, {-0.15, 0.15}],
{x, 0, (3*Pi)/2, Pi/15}, {y, 0, (3*Pi)/2, Pi/15}],
MeshRange -> {{0, (3*Pi)/2}, {0, (3*Pi)/2}},
Ticks ->
{Range[0, (3*Pi)/2, Pi/4], Range[0, (3*Pi)/2, Pi/4],
Automatic}];
