The scope isn't going to tell him how much current he is drawing without a special current probe or a low resistance shunt on the input.

However, I do agree with trying the internal RC oscillator, and make sure you have your fuse bits set for the right type and speed of crystal oscillator. Do you have any capacitors to ground on the crystal? The datasheet for the PIC should be able to tell you what size, but I think normal is the 10-20pF range.
