Difference between にしたら /として/にとって


As I understand it both にしたら and にとって mean "~ from the point of view of ~".
What are the differences and if there is a similarity between either and として
and is the difference between them ?

As @Peri says, each of them means different.  
**として** is basically ' ** _as_** ': 先生{せんせい} **として** 働{はたら}く (work as a
teacher).

**にしたら** has the sense of conditional. Yes, you have it right; it means
something like " ** _from someone's perspective._** " We would say ネコの身{み}
**にしたら** いい迷惑{めいわく}というものだ. (From the perspective of the cat, it must be an
annoyance.) We would also say ネコ **にしてみれば** 迷惑な話だろう. Actually, many similar
expressions are possible: にすれば, からしたら, の立場に立ってみれば, etc. But all these tend to
sound rather informal except maybe の立場からすると.

**にとって** is, yes, ' **for/to** ' though we don't use this to mean 'made for'.
We use this in, for example, 私 **にとって** 大切{たいせつ}な人です (S/He is important to
me), or この街{まち} **にとって** 観光産業{かんこうさんぎょう}は重要{じゅうよう}です (Tourism is important
industry for this city), わが社 **にとって** (For our company).
