Sorry, I realised I haven't replied to anyone these few months. (I was having too much fun on exchange in Japan
)

Yea, in relation to intransitive v transitive you got that correct!
Also your question on には, I think you got your answer too. You would use に or で normally, but if you wanted to make the noun before it the subject/empahize the topic of the sentence you would add は to the に or で.
(FYI には can also be used similarly to the grammar pattern ために but it is POST VCE so it will probably confuse you so you can ignore it)
With ちがいます, you should use とちがいます when you want to say something is different from something else in a comparison
ie: 私はサラさんとちがって、すしが好きじゃないです (Different to Sara, I don't like sushi)
or you can use がちがいます to say something is just different.
そのことばのいみがちがいます! ( The meaning of that word is different!)
