Add ON HTML scripting and Signature ?

First question, I want to add-on a Java chat, and have the scripting foor it, I need to discover where to add the script to have it display on the header.

Second, I have heard that you can enable two signatures. Is it possible, or is it possible to increase the maximum number of characters on the signature field?

I have solved the HTML add on chat issue.

How do I go about adjusting the permissions of added links?

I do not want a non registered user to see the links I added on.

You can edit the permission of a topic so that Guests(non registered users) won't see it. To do that go to admin panel=>Forum=>Permissions=>Forum Permissions control from there choose the topic you want to edit it's permissions and make sure that this option "Read the topics" isn't checked for Guests.
