Disputed. Most people use Erasmian pronunciation, which is described in all the Greek Primer PDFs here on Textkit. This web page
has a list comparing Erasmian, probably ancient Athenian and biblical pronunciations.
secondly, writing in greek is like that of latin, from left to right, right?
For our purposes yes. Very ancient inscriptions can go either way, or even both directions.
thirdly, i hear there are a lot of irregular verbs in greek, is that true?
