Can you speak Russian or Romanian? That would be you main problem here, because not too many speak English. It's safe to live in Moldova, but normal precaution is needed because in any society there are people who are trying to steal. No guns are allowed in Moldova, besides hunting weapons. I would say less than 1% have guns.
It's not making sense to buy or rent a car here. Cars are more expensive than in USA and the gasoline is 1,5$ for one liter(quite expensive in my opinion).
High education is OK. Some foreign students study medicine in Moldova(in English), but it's not recognized around the world, so you will have to get an upgrade on your education here.
Most apartments are furnished and the cost starts with around 150$. I can give you a couple websites with classified, but it's not in English.
Currently I live 70km from Chisinau. I don't go to clubs but I know there are good quality ones. I would say it's up to 10$ to enter.
