Does "not so fast" mean "don't go so fast"? Can I shorten the sentence like this in other situation as well?

Yes, you are correct. "Don't go so fast" can be shortened into "not so fast" when speaking. You can do this with similar sentences. Ex: Pedal the bike. (Go) a little faster. Ex: Mix the eggs and flour until it's well combined. (Mix) gently.
