Howf seems to fit OK (though I've never heard the word before!) and links nicely with "awe struck". I think Anthem (which I had considered - also Anthea) must be the other one as it fits with Heal for 7 down. But why it should be Anthem based on the clue has eluded me.
Just seen Gen2's answer which seems to fit the bill more precisely. So, I now have Slur for 7 down, Anchor for 11 across and Howf for 2 down! All done!!
