Scheme seems fine to me, try to place crystal closer to the PIC and shorten it's leads (not PICs leads, the wires that connect PIC and crystal).
I agree, the layout is absolutely horrible - personally I don't like (or use) breadboards, and this gives a good example of why not 8)
You should keep leads as short as possible, particularly round the crystal and associated capacitors - check the veroboard layout for the 876 board in my tutorials, you will see how close I place the crystal to the pins!.
