@Pecoes - The changes were made to enable global and user level changes to Special:Chat in the same way we use MediaWiki:Common.js and /User:USERNAME/common.js and their css variants. The chatmod icon itself only requires MediaWiki:Chat.css to be imported, but when we tell users how to add the script in, we tell them to c/p Chat-edit-count which loads the runescape wiki Chat.js/load.js, which already loads the other scripts/stylesheets anyway. Full credit should go to User:Joeytje50 who also has a relatively easy guide to how to add the icons yourself.

@WieQuadrat - I believe the only way to alter the user links would be with javascript.

Question 3 can be achieved with help of the chat-edit-count script loading, where you can take advantage of the custom chathacks Pecoes mentions above to do something like /welcome USERNAME as a message which would output the message you wanted. Place the script in MediaWiki:Chat.js for it work for everyone.
