Advice on seal/other parts replacement when changing the front CV axle

[SamW]

Going to have the front left CV axle replaced soon. Not doing this by myself but gathering the parts and letting the local indy do the job.

I'm a bit unaware what should be changed with the CV axle while in there so looking for some advice to get it right at once.

-Naturally the CV axle itself (seems like some manufacturers include the axle nut with the axle, and if not, I guess it should be bought separately and replaced?)
-Differential output seal (part number 7 in the picture?)

Is that all or is there something else to replace which shouldn't be reused?

Thanks.
