Eric,
ContourPlot is one convenient method for making your plot.
Needs["Graphics`ImplicitPlot`"]
Needs["Graphics`Colors`"]
f[x_, y_] := x^2*y^2
ContourPlot[f[x, y], {x, -5, 5}, {y, -5, 5}, Contours -> {1, 2, 3, 4, 5},
ContourShading -> False, PlotPoints -> 30, FrameLabel -> {x, y},
PlotLabel -> f[x, y], Background -> Linen, ImageSize -> 500,
Epilog -> {Text[1, {0.802016, 0.843527}], Text[5, {1.72142, 1.69221}]}];
