I am wanting 26a to be Fly Half which is the No.10 in Rugby Union, and it is 3,4,,,,, but it disagrees with a lot of your letters, and I can't parse it apart from the fact the letters are there and in order
F(reakish)LY HA(u)L (of)F

[JJ109]

42a must have something to do with "prestidigitatiors" - but again, I cant work anything out, presumably removing some letters???

If people want to give assistance, it will help to know that an extra letter is produced by the wordplay in every clue.

All of Matakari's suggestions except one have mistakes.

Matakari, being blunt, this is at the easiest end of the Crossword Centre puzzle range. You have plenty of time. Why not persevere a bit by yourself.

You forgot this

"An extra letter in addition to those belonging to the entry is produced by the wordplay of every clue. These, read in order, give an instruction"

That explains why it isn't Dee car BS!

14a Neon (your G is wrong)

45a Less (reflected = ssel, but the 1st S is the extra letter = sel, sace = en, i a(rea) (unk)n(own) = Selenian (of the moon)

Apologies for not mentioning the preamble with the link!

What are you wanting Matakari? Is it just the additional letters?

[klazomaniac]

As I have explained Matakari, I have not done this crossword.
So these are only guesses.

15a Art + I + Clefs (F is superfluous)
30a Dee + car +BS (E is superfluous)
4d Snipes (E is superfluous)
16d Crammed (C is superfluous)

[klazomaniac]

19d E ra ton (N is superfluous)

[klazomaniac]

23d Sacco + C [reversed] = Cocas (C is superfluous)
