I would try and gently push a lead that you think is the correct size slowly gently back up in the lead sleeve as the correct size should be a good fit. While any paper will do in a pinch, using a smoother paper will give you more precise control as you add graphite to create values.

Like other hard graphite lead pencils, 6H pencils work well for preliminary work, as well as for fine line drawings.
