Are the ring and pinion gears the only two parts I'll need from the MGA? 

Yes, I think, but never personally having done it, I'd say get another

4.3 and 4.1 in the literature. Is he mistaken?

Maybe?  The 4.55 ratio was a performance option for the MGA, available on a
new car at the time, but statistacally not very common.  So could be, or
maybe not.
