The details for pulling a W201 airbag wheel are well documented on 2Phast's site. I strongly suggest that you get a helper to hold the wheel while dealing with the 10mm allen head bolt and don't leave the steering column in the locked position.

As for pulling cluster needles, all you need is a pair of clean spoons to act as rocking pry bars to lift the needle slowly off the pins. Some people use other cutlery, like a fork, but I think the spoons give more control and equal pressure on two sides of the needles.
