We present an effective theory for the bulk Fractional Quantum Hall states inspin-polarized bilayer and spin-1/2 single layer two-dimensional electron gases(2DEG) in high magnetic fields consistent with the requirement of global gaugeinvariance on systems with periodic boundary conditions. We derive the theoryfor the edge states that follows naturally from this bulk theory. We find thatthe minimal effective theory contains two propagating edge modes that carrycharge and energy, and two non-propagating topological modes responsible forthe statistics of the excitations. We give a detailed description of theeffective theory for the spin-singlet states, the symmetric bilayer states andfor the $(m,m,m)$ states. We calculate explicitly, for a number of cases ofinterest, the operators that create the elementary excitations, their boundstates, and the electron. We also discuss the scaling behavior of the tunnelingconductances in different situations: internal tunneling, tunneling betweenidentical edges and tunneling into a FQH state from a Fermi liquid.Comment: 27 pages; new subsection with summary of results and two tables.  Misprints and errors of an an earlier version are corrected. In particular  the tunneling exponents for the SU(2) states at 2/3 and 4/7 have been  corrected; same with the electron operator for the 2/3 stat
