For your first question, you must run a formula on all the atoms in the structure as drawn.
Formal charge = Valence of the atom in question - (number of non-bonded electrons + number of bonds)
The only interesting one is the oxygen, (but you can do them all, they ...
Formal charges of atomic structures are discussed. The type of bonding that occurs in H-CH2-OH is analysed.
