Yeah, and reading Latin is complicated by the fact that Latin authors like to put the adjective and its noun on oppposite ends of a phrase and then stuff other things in between. So, instead of "the yellow car in my driveway that belongs to my brother" they'll say "the yellow in my driveway that belongs to my brother car". Because an adjective must match its noun in number, gender and case, the authors think of the noun and adjective as holding the phrase together. And this is only the beginning: in poetry there are even fewer patterns because the words are generally ordered to fit the meter: the only thing you can really count on is that certain particles must be the second word in a sentence (important because the manuscripts didn't have punctuation) and that a preposition always precedes its object.

Yes, in most cases the sentence will still mean the same unless it's a very complicated sentence with multiple nouns and adjectives where there may be some ambiguity as to which adjective goes with which noun (and that too only if declensions happen to be in the same case). Having said that, the most common sentence structure used is still subject-object-verb.

It is for the most part (see answer above).
