Pronunciation of Г

[wolfie-18.livejournal.com]

When English works are translated in Russian, such as "Гамлет," does it still retain the English sounding H or does it change to "Gamlyet?"

Also, I've noticed around that the Russian's version of "haha" is "гыгы," which sparked this question. Would that laughed be pronounced as "huiy huiy" or "guiy guiy?"

And now that I'm on the topic of pronunciation... the "hard sign" that appears in съесть... does that c have a syllable all on it's own? I.e. "Suh-yest'"
