If TOR is set up, will that solve the possible problem with inbound connections?
TOR will allow you to have inbound connections without doing any network adjustments.
It is important to clarify the difference between an incoming and an outgoing connection though. An incoming connection doesn't mean that you don't receive anything from other nodes. It just means that the node that will initiate the connection process will always be yours. Once the connection between two nodes is established, it doesn't matter who initiated it or not. The transferring process will be the same.
Finally, TOR is often slow. This is just a side-note.
