Me thinks you have A/C issues. First, condensation in the A/C system is "funneled" out of the car and usually drips in two places under the car. Each one is near the bell housing, one on either side of the bell housing. NORMAL when you drive with A/C on.
If you are getting a "drip" on your foot (or the passenger is), there is probably a rotten rubber tube under the dashboard or a part that has slipped off. This is a possibly a difficult drip to find. You will have to get access under the dash and look for dripping condensation. It should ALL be channeled down and under the car. Sometimes the end of the rubber tube (which closes based on its design) may need cleaning ... not at all difficult to do.
The dirty socks smell is very common. Mildew. You will need, most likely, to find something to clean it out, and there are products available, I believe. BUT, you might get by, and you should after getting rid of the smell, change the way you run your A/C. Always, turn it off about 2 minutes before shutting off the engine. That will reduce the amount of moisture that normally builds up. (Warm dry air circulates for 2 minutes to dry out the moisture.) Mine used to do the same thing (and, other of my BMWs smelled the same way), until I began to shut them off 2 minutes before stopping.
