@TS - In Islam it is work this way:

1) Non-muslim male cannot marry with muslim female, unless he converted.
2) Muslim male can marry with non-muslim female, without the female convert to Islam.

For your name, As long as your name gave a good meaning, it is ok to not to change your name. It is not a sins but it is ADVISED to change it so that, people know that you have converted.

For your parents funeral, you may do whatever it is as long it is not against the Islamic Teaching.

It is doesnt matter if you go anywhere (when spore/us didnt implement syariah law), but your future wife is a good muslim(ah) practicer, she should understand and make you understand about this matter as this is what has written in Quran and agreed by the Muslim scholar.

@xonius: i do think at malaysia, they are better than the arabs.. if not.. how could PAS coop with DAP.. haha (another issue)

& for TS, do consult this matter with Dr Mohd Asri Zainul Abidin (Dr Maza). http://drmaza.com
