yantao,
I hope this will help.
First I must warn you that it is wrong to convert to muslim just because you want to marry her. If you don't understand ISLAM at all, then there is no point for you to convert. In fact you don't even need to do that just to to marry her.

THE MUSLIM CONVERTS' ASSOCIATION OF SINGAPORE . you can find everything here.
Once your understand the beauty of ISLAM and became a MUSLIM then, THE ONE AND ONLY will lead you to the right path and I am sure your Mom will understand.
I don't think I am the right person to teach you ISLAM, so I leave this to the brother at Darul Arqam
THE MUSLIM CONVERTS' ASSOCIATION OF SINGAPORE.
As for your name, don't worry, do you know that there are millions of CHINESE MUSLIM with chinese name in this world who can't speak a single words of Malay.

Anyway hope all these info help and will lead you to the right path
