note - your function is not defined for x,y=0
for the first question where the ContourPlot generates an empty graph you need to change the line to
ContourPlot[f[x, y] == 1, {x, -30 Pi, 30 Pi}, {y, -45 Pi, 20 Pi},
Axes -> True]
(* i.e., include the argument x,y in the call to f *)
for the second question, you need to use graphics primitives yourself and actually repeat what PlotLegend does. This is a task too large to answer as a forum question
