What is the meaning of this sentence?

"Anata ga sou ome ni kakatte kudasatta node, zekkõchõ desu."

I get it that this structure means in kenjougo form something like "Just by meeting you, I felt all great" or something along these lines.
Can someone explain the
<~te kudasatta> line?
Has it the same meaning as in <~te kurete>¿

I don't know where you got it from, but the sentence is wrong.

1)
Indeed おめにかかる is kenjōgo of あう. Thus, the subject must be the speaker or the speaker's in-group member(s), and the direction of the respect is from the subject to the object/target.
e.g.
きのう、わたしはせんせいにおめにかかった。
Yesterday, I met my teacher.

the subject: I
the target (object in the English sentence): my teacher
the direction of the respect: from "I" to "my teacher"

As you can see, the recipient of the respect is indicated by the particle に for おめにかかる. However, が is attached to あなた in your sentence, thus, it shows that the respect is from あなた towards someone else.

2)
～てくださった is the past form of ～てくださる, and くださる is an honorific verb (そんけいご) of くれる. The respect is from the speaker to the agent of the action.

3)
そう doesn't make sense there.

The correct sentence should be:
あなたにおめにかかれたので、ぜっこうちょうです。
or
あなたがおあいくださったので、ぜっこうちょうです。
(note: "お + -masu stem of a verb + くださる" is more polite than "-te form of a verb + くださる".)

thanks a ton it was something someone said to me, perhaps I misunderstood it, since the "anata ga" part was kinda weird to me.
Perhaps it supposedv to mean something like in this following pattern:
"anata ni ~~ koto ga", with the <koto ga> emphasizing the matter. I remember to read in my textbook that the <koto ga> pattern is used in conjunction with occurences in the past, like in the original post.

You must be confusing ～ことが probably with a set phrase ～たことがある or something. ～ことが is not used only for past things. For example, there is no problem with the following sentence.

あなたにあしたあえることがたのしみです。
I'm looking forward to see you tomorrow.
