Microsoft Office Junk

So I recently got my very first Macbook Pro!
I didn't order Office, so I had to get it through my school. This, however, forced me to download everything in the suite.
Now since this is my first Macbook I am really weird about having things on it I don't need that will only take up space.
I only wanted to keep Word and PowerPoint, so I deleted all the excess weight from the other programs (Excel, Outlook, etc.) but there's still certain aspects I'm unsure whether or not I can get rid of.

If anyone has the knowledge to help me figure out what can stay and what can go, I've attached a screen shot of the file.
I know this may be a stupid or weird request, but it's going to bother me if there's stuff on there that's only serving the purpose of taking up space.

I'm use to being trolled on the Microsoft forums when looking for help, so please be gentle.

Thanks!
