If I have a system of bosons described by a wave function that can be separated into a spatial function and a spin function, do the spatial and spin functions have to be both symetric? Or can they be anti-symetric and symetry be attained only when we consider the whole wave function?

The whole wave function must be symmetric. The components may both be antisymmetric.
 
With more than two particles things become more complicated. The space and spin wave functions can have mixed symmetry, neither symmetric nor asymmetric. The net function must be symmetric, though.

If we release an electron around a positively charged sphere, the initial state of electron is a linear combination of Hydrogen-like states. According to quantum mechanics, evolution of time would not change this initial state because the potential is time independent. However, classically we expect the electron to collide with the sphere. So, it seems that the quantum and classics predict different behaviours!
