Naw - what you did was fine.
Not many services really use ident anymore... and having port 113 set to "stealth" means that when someone tries to talk to you over that port, it gets no response. So whatever is trying to talk to port 113 will usually just keep waiting for a response... most will timeout, but it may be a while.
Setting it to "closed" makes your firewall say right away "rejected" and whatever was trying to connect will usually just go on with it's business, since it actually did get a response.
Hope that helped.
