I think there are two ways to type Korean: 1/ Use online Korean keyboard: http://www.branah.com/korean 2/ You can install Korean keyboard on your computer: http://easykoreanlearning.wordpress.com/2011/05/17/how-to-install-korean-language-on-windows-xp/ Good luck to you! ^^~

First, you should learn Hangul(한글) first. We do not use Romanization. So it will be hard to understand romanized letters, and there is no way of adding romanized suffixes as well. So, first try to memorize 한글(Hangul, the Korean letter system, the Korean alphabet) then there are several 조사(토씨, postpositional words) which you can learn and use to expression your thinking in Korean precisely. Your question is too big to answer, so please narrow down to some cases then you will get better answers.
