Hi, Lene, and welcome to the forum. Please take a minute to click the user cp link and complete your BW profile to include vehicle and location information as that is quite useful.
If you scroll down into the sedans section, you'll see a sub-forum for the W210, which is specific for your car. There you'll find a wealth of information on lots and lots of topics about the 210. A bunch of great help/DIY stickies and the search function will yield still more.
Re: cats, I just went through the same thing. The stock cats were junk, MB extended the warranty period for AMG models, but the rest of us are left to twist in the wind. Since you're in CA you have only two choices: go to an exhaust shop and have them weld in an aftermarket cat that meets CARB/OBD-II specs or buy the oem components from the dealer. I ordered mine online from duvalmotorcars.com and bolted them in last Friday. The reason they are so expensive is that you actually have four cats, 2 on each bank, so when you buy from the dealer you're getting two cats as well as the stringer pipes, etc (replaces everything from the exhaust manifold to the resonator). 100K is also the suggested interval for O2 sensor replacement, although if yours are okay (no CEL, no codes, no loss of fuel economy) you can stretch that.
Anyway, more to come down in the 210 forum and we'll look for you there.
Take care and enjoy the ride,
