revelateur = developer
fixateur = fixer

The fomacitro is a stop bath, it is not truly necessary, but is the normal step between developer and fixer, and is recomended.

I think you will need in addition some sort of measuring cup or graduated cylinder to measure the amount of developer your are using in the tank, it will be more than 100 ml so 1 litre would be better for that. The smaller one would be better for measuring concentrates before mixing I think.

Are these chemicals fresh? If not, I wouldn't buy them used, they are perishable. Same thing applies to the film.

Another step you mind want to include is hypo clearing agent, after the fixer, which will assist in the washing out of the fixer from the film. This is optional, but reduces the wash times.
