Moving logistics - advice needed

My family will be relocating to Korea in about 2 months and I am clueless with the entire moving process and dealing with emptying my current home.

Can anyone recommend what I must bring from the states to Korea?  I am planning to bring my Samsung curved tv since it is new.  Do you know if I use the transformer/converter, it will work in Korea?

I also have lots of junk in the house which I need to get rid of or put into storage.  Any suggestions on how to deal with the stuff that I am not taking to Korea beside garage sale or online postings?

I would take any suggestions and thanks in advance.

To be honest, I would worry more about customs:
