For emoticons, just go to MediaWiki:Emoticons.

For chat, you're going to have to be a little more specific, as there are a few places, and they all have different places to change each one.

Here's what the options are: http://prnt.sc/deasqw

And for to change them, go to MediaWiki:Chat, MediaWiki:Chat-join-the-chat, MediaWiki:Chat-live2, MediaWiki:Chat-start-a-chat, and as for the part where is says Community Central, that requires a CSS code, which I can give you if you'd like. As for the rest, all of them except MediaWiki:Chat are not whitelisted, which means that you cannot edit them yourself even if you are an admin, so you'll need to contact Staff at Special:Contact/general to change them for you.

I hope that helps!
