Hi Tyke, thanks for persevering! The definition in 8 is in part carried over from the previous clue, so in full reads “printer’s material in Russian”. Wordplay is an anagram with one letter subtracted.
In 9, the references to “6” and “10” are
not cross references to other clues. The definition is “vine-leaves by design”. They might be found at the beginning of ancient manuscripts as embellishments to the first letter.
