If the principal quantum number of a shell is equal to 2, what types of orbitals will be present? Is it s and p, or just s? Also, if the principal quantum number of the outermost electron of an atom in the ground state is n=3, what is the total number of occupied principal energy levels contained in the atom? Is it 1, 2, 3, or 4?

the principle quantum number can be thought of as the energy level you are dealing with.. so yes 2 would be s and p since they are both in the 2nd energy level... 1 has 1, the s... 2 has 2, s and p...3 has 3, s,p,d... 4 has 4, s,p,d,f... etc... the orbitals can be named s,p,d,f,g,h, etc...
if the outer most energy level in the ground stte is 3, then it has 3 types of orbitals being used.. maybe not filled to capacity, but used...
if looking at the periodic table, anything elements in row 1, H and He, are using only quantum number 1, they have 1 energy level used... row 2 is using 2 quantum numbers.. the 1s and the 2s,2p... so elements in the s and p region of row 3 use the s and p orbitals, and the elements in the 3d region (4th row transitions elements) use the 3d orbitals...
this is much easier when showing, rather then typing, but if you need more help contact me.
