Conjuctions, Interjections (근데, 그래도, 하지만)

[matthew254]

I would do the happy dance if I could get a lesson on the appropriate instances to use:

그런데 (근데)
그래도
하지만
그렇지만
그러면
그나마
그러마
그래서
그럼 (그럼요)
그다지

and any of the other thirty words I'm missing. It's a bit daunting. When to use each one? Which ones are most common? Do any carry a certain connotation? Are any considered to be more polite? less polite?

그러마 is different with the others.
It's just a plain statement of approval saying by elders to younger.

그러마 = 그렇게 하마 : I'll do it so.

ex.
그 자리에는 내가 가마.
I'll go to the place.
Let me go to the place.

돈은 내가 주마.
I'll give you the money.
Let me give you the money.

I second Matthew's suggestion!
