Because internet is set via a router, I need to forward some ports for some application to connect to internet. Ususally they state that I can pick any port number to forward, but I have no idea which ones are safe, and when I might accidentally open up too many ports. So how do I set a port correctly without making it vulnerable to outside attacks?

There really is no way to open ports safely, as long as they are open and not stealthed they remain a vulnerability. Some ports are well known for certain programs so if you change to a non common port you have a little more protection but anyone scanning your IP address can still find it, they will just have to look a little longer.
