I believe the answer is:

newscaster

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

'tv personality' is the definition.
The definition and answer can be both people as well as being singular nouns.
Maybe there's an association between them I don't understand?

'about to appear in remade westerns' is the wordplay.
'about' becomes 'ca' (abbreviation for 'circa').
'to appear in' indicates putting letters inside.
'remade' indicates an anagram.
'westerns' with letters rearranged gives 'newsster'.
'ca' going within 'newsster' is 'NEWSCASTER'.

Can you help me to learn more?

(Other definitions for newscaster that I've seen before include "who reads the headlines?" , "Baker, perhaps" , "TV regular" , "TV presenter" .)
