Ok, here's some collected thoughts (yet again). What have we got?

1) 0=0A=10BABYA=36 (0=0 A=10 a=36)

I am 95% certain this is the description of a mapping of [0-10A-Za-z] to numbers starting with 0. It tells you the three starting points of each substring in the list. All other interpretations that I have seen make no sense to me.

This mapping could have two uses: character shifting or transformation.

2) The hidden XMP data.

This seems to cross out all the data on the left. It also crosses out the 51 byte string. Lastly, it appears to highlight the positional codes in the RT. ASCEN section (or possibly cross them out). It even points at the 6 in '36' which seemed noteworthy since 6 shifts is what's needed to turn the z into a 5. OP went to the trouble to hide this XMP data so we should assume that it must somehow hint at the solution.

3) z69JZqlJn862D1ndx7oLVEMmVOlP1zewEeUCrsI7Roahzpeny7P

Most of us have shifted the hell out of this in various straightforward ways. Several of us have used the WOW signal strength as an alphabet cipher key, and at least a couple of us have used series of timecodes over on the right as a cipher key. It either doesn't want to want to turn into a private key address, or we're barking up the wrong tree.

Interestingly enough, it appears to be vigorously crossed out by the XMP. This made me wonder if there is some sort of 3733T instructional message hidden in it, but I wonder that less and less with OP's more recent hints.

4) CHANNEL NUMBER (TWO DIGITS, WRITTEN VERTICALLY)

This was recreated by OP for this image, but was text from the original document. It's possible that OP preserved it as some sort of hint. That said, most instances of "two digits, written vertically" are crossed out by the XMP.

5) Some timecode and other data on the right

This stuff is not crossed out by the XMP, some of it seems to be specifically called out by the XMP, but it's not clear what to do with it. It seems worth calling out because I think it's been largely ignored.

6) Various OP clues

"Final countdown" - Either we're near the end, or it is somehow referring to the time codes that are called out in the XMP.

wow + crops - we need to use something from the Crops puzzle. I am assuming the character map, but could there be more?

6EQUJ5 - This is the Wow signal strength. We must need to use this somehow, but it doesn't work as a key.

No sha or hash needed - any transforms we solve will be relatively straightforward

the prize awaits you
the final palindrome is key: hints at wow being a cypher key?
once small is now tall: all uppercase?
