"Removing the hub isn't too hard I'm hoping."
You don't actually have to remove the hub, if repairing on the car. You probably will find it difficult with that amount of rust around, if they've not been off before.
If you haven't done it before, there's quite a lot of work involved. For example, you need to disconnect track rod end and lower arm ball joints from the hub carrier (and these can be a real pain if rusted in), it may be worth your while getting a Haynes Fiesta manual. You'll also need a pair of circlip pliers.
Good luck.
