Not sure about the pianos vs tomatoes question, I guess it is just an irregularity.

Did you mean 'You're finished'? If so, it is just an adjective (can't imagine a passive interpretation, unless we add 'off': He was finished off by whatever (you can tell my imagination is going at a rate of knots here LOL). ('Your finished...' would also be an adjective, modifying/coming in front of a following noun, but the 'finished' would likely be known and assumed in the context, and thus left unsaid: Your (finished) book is really good!).

'You finished' is a pronoun and verb (verb is Simple Past), but it could also be a case of the speaker ellipting 'are': You('re) finished? (It is not passive).

Some words ending in o have es plurals.
tomatoes
potatoes
echoes
heroes
negroes

Nouns ending in a vowel + o have s plurals (radios, zoos), but so do the following.
commandos
concertos
Eskimos
kilos
logos
photos
pianos
solos
sopranos


A few common words ending in o can have both es and s plurals.
buffalo
mosquito
tornado
volcano
