Sorry to hear that. I hope that you did a complete wipe, format, and re-installation from trusted media.

Good. Doing it correctly the first time will save you the hastle of rebuilding it again.

Use the following general format to open up ports:
iptables -I INPUT -p tcp -dport XXX - j ACCEPT

where XXX is the port you want to open. Though I would recommend limiting access only those IPs which you need to allow connections from (if that is at all feasible). If you don' t mind me asking. what are you planing using port 2223 for?
