として means "as", "in the role of": the noun before it is the capacity in which someone acts, or the thing something counts as. It goes straight after a noun.
Before another noun it takes の: としての.
として gives the role a person speaks or acts in. にとって gives the person something matters to: "for me", "to me". English has "as" for one and "for" for the other, but learners still swap them.
These go beyond として on its own.
With は, としては sets a standard to judge by: "for a…". It has its own entry.
