Well off, hiding nothing and gawping with awe (4-4)

I believe the answer is:

moon-eyed

I'm a little stuck... Click here to teach me more about this clue!

'gawping with awe' is the definition.
I can't tell whether this definition defines the answer.

'well off hiding nothing' is the wordplay.
'well off' becomes 'moneyed' (I can't justify this - if you can you should give a lot more credence to this answer).
'hiding' is an insertion indicator.
'nothing' becomes 'O' (looks like zero - 0).
'moneyed' placed around 'o' is 'MOON-EYED'.

'and' is the link.

Can you help me to learn more?
