comment Basic doubt in a free boundary problem for the Laplacian
In the question you refer to p-Laplacian but in the equation you use the 2-Laplacian. Is that correct?

comment Extension of Sobolev Functions
Suppose Omega is, say, a square or cube, and u(x) = x_n. Can you solve your problem in this or other simplified situation?

comment probabilistic interpretation of elliptic equation with mixed boundary condition
How much do you already know? Can you establish the probabilistic interpretation in a simpler situation, and if so, why is this more difficult?

comment Mountain Pass theorem for minimization problems with constraints
Linking theorem might be useful. The aforementioned references should contain relevant material.

comment Mountain Pass theorem for minimization problems with constraints
There are generalisations of the theorem: see for example references [17] and [24] in master's thesis of Eero Ruosteenoja: jyx.jyu.fi/dspace/handle/123456789/41049
