subject/object pronouns following preposition

When a pronoun following preposition is understood to be the subject of a verb that is implied but not stated, is there a rule about which pronoun to use? For example:
She is taller than I am. So, She is taller than I. (Not: She is taller than me.)
He went to the restaurant after we went there. He went there after we???

Does the pronoun following the preposition depend on which verb it's implied to be the subject of?

'unless' and 'if ... not' have the same meaning?

Hello everyone,
I am reading in Longman Dictionary of Contemporary English. They wrote:

---------------------------
WORD CHOICE: unless, if ... not
Use 'unless' to say that something will happen or be true if something else does not happen or is not true : Unless they get protection, they will not testify.
!! Do not use the future tense after 'unless' : I won't go unless you go (NOT unless you will go).
!! Do not say 'unless if' : Don't call him unless it's urgent (NOT unless if it's urgent).

What should I do

"Little" Vs "Few"

The Words "little" and "few" mean the same .
What exactly is the difference between the two?
Till date I was of the view that "little" is used to denote uncountable quantity and "few" is used to measure "countable" quantity.
Any other differences between the two.
Please clarify.
