A/C Problems and Engine Code Issues

Hey everyone, I just bought my first MB C 320 an 01.

I bought it monday, but I looked at it on sunday and everything was working fine. cold a/c and no engine code(s).

Yesterday, I tried to recharge my a/c with a recharge kit from autozone (never done this before) and then it did not seem to work right away. I then drove the car for no longer than a minute and a puff of white smoke came from my engine bay and don't know from where since I was driving. Then, later on after letting the car rest, my a/c started blowing cold air. but now the problem is that it'll sometimes blow cold air and sometimes warm air. why is it doing that? what can I check? I took it to a mechanic who used to work on my Honda S2000 but he said he wont touch a benz lol. I'd rather work on it myself anyways so that I save a few hundred bucks. where can I start looking? Also, it makes a clicking noise behind my dash somewhere, what can that be?

Also, I got the engine code read to me at autozone and it read P0422 and P0432? I do not understand one bit of this ha. I'm a noob still. I did try to clean out MAF but the engine code did not turn off? How do I get the code to come off? Autozone wont take it off for legal purposes, which is understadable. Is the car supposed to automatically reset?

Thank you guys for your help
