Sulfuric acid can be produced in the laboratory by burning sulfur in air and dissolving the gas produced in a hydrogen peroxide solution.
SO2 + H2O2 → H2SO4
The above is wrong right?

The equation is balanced, and I believe the oxidation will take place, at least to some extent:

no, im fairly sure the equation is correct as the oxidation numbers for all the elements involved balance 
Also this should probably be in beginnings

Your equation for the reaction is correct. Nitric acid can also be used instead of hydrogen peroxide, and it has the added benefit of giving an
indicator when it has all been used up/reduced (no more NO2 gas is evolved). You can then swap out for more nitric acid and have a very
efficient synthesis. When using peroxide, you have no such indicator when all of the peroxide has been reduced. Still, peroxide is much easier to come
by than nitric acid...

Here is a nurdrage video on this subject. It i svery well made and relies on this principle.
My advice: If you can, use nitric acid instead of hydrogen peroxide.
