You need to query the option table, then make a separate query for the user, then iterate through all the query options and when you come to one that the user has checked, you simply add the checked="checked" attribute to that checkbox tag. You can hold that bit of information in a variable, so to use it in a template.

I don't have time to write out the code for you, but I'll see what I can do later today if you still need help.
