I have a busted right strut mount on my 93 300SL and the shop is telling me that the labor to replace is $225. Is that high? Also should I replace the struts as well since there will not be a charge for that since the struts must be removed anyhow according to the shop. The car has 113,000 miles on it.

Also I had a stalling problem and the shop replaced the ignition control module ($1100+ price tag for the part) and now when I turn my ignition to the on position the lights on the dash will sometimes stay on (keep in mind I am not starting the car just turning the switch to the on position) and other times they go off. I notified my tech and he told me to bring it back in. Has anyone every experienced this.

$225 to replace the strut mount is ludicrous. You do not have to remove the strut in order to replace the strut mount.

To do it yourself you'll need a large hex key (forgot size -- 5mm?) and an open 22mm wrench. (size for my 300E, not sure if same for your MB)

Remove tire. Jack the car up on the broken strut mount side high enough to place a jackstand underneath the A arm and lower slowly to compress the strut more than the natural weight of the car would.

Now hold hex bolt (on top of strut) in place while unloosening the 22mm bolt that holds the mount on. If the strut begins to recess downward as you're undoing strut bolt, then you'll need to lower the car jack to put more pressure on the strut/A-arm, while keeping jackstand in place.

Good luck!

I’m also not sure of the size for your car but on mine (87 190E 2.3) was a 7MM and 22MM. Anyhow the tools look like these:
