Answer 1

Vim has excellent help files.

I had no idea what the answer was to this question but I found it in one minute:

1. :h cterm (don't hit Enter yet)
2. Tab for auto-completion to see some choices
3. highlight-cterm sounds promising so tab over to it and hit Enter
4. Hmm, cterm={attr-list} and See above for the description of attr-list
5. That last "attr-list" is highlighted as a tag so put cursor over it and hit Ctrl+]

And voila..

attr-list is a comma separated list (without spaces) of the following items (in any order):
        bold
        underline
        ..etc..

So cterm=underline,bold is the answer.
