I was in the same situation as you, and I've found that when in doubt, 
it is best to open up form.inc and look for theme_<#type>, e.g. 
"theme_checkbox", "theme_select". Then you can see what HTML is output. 
If you still can't figure it out, remember (or look for) a core form 
that is similar to the one you have, and see how it is made ;).

By the way, about your checkboxes... #tree is indeed a way to get 
arrays, but remember that if possible, you should use the plural 
checkboxes and radios types.
