sounds ok to me, you dont have to use a glaze as a rule but it does enhance the finish after polishing and it also aids bonding for the wax,
sealants are good to have tbh they've got very good uv protection, they have very good durabilty but lack in terms of gloss, they leave a nice glassy shine on silvers/light coloured cars, and are very good for protecting non clearcote paints ie mk2 golfs/polo's
