What is the white thing called and will it just be a simple matter of
removing the toilet and replacing it.

It's a straight pan connecter running into a sawn-off piece of solvent

filling solvent cement has been liberally applied! What a ghastly
looking job. Look at the overflow, too! I'm sure you can improve this!
