I opened:

TCP: 443,5061,50000:59999,3478
UDP: 443,50000:59999,3478

Did I open something that didn't need to?

50,000 - 59,000 are only needed if you are federated with a partner who is using Office Communications Server 2007

I think that 443 is the main one and 5061 if you are going federate.
I don't think that we opened 3478.

Here's the page that I am using to get the information:

The important question is what are you trying to support?  Lync uses different groupings of ports/protocols for different use cases (server-to-server, client-to-server, client-to-client) so understanding your topology is key.

The link you provided is for the Edge Server which does not cover internal servers.  More details about your topology will help here.
