Re: <<Nusach Sefard has (in shacharis) "Nakdishach v'naaritzach",
conforming with the sefardim. They do say "ham'shalsh'lim lecha kedusha".
I can't remember whether Sefardim say lecha or lach there.>>

Sefaradim do say leKHA kedusha - followed by 'al yad neviAKH.

Many of the Ashkenaz lekhas are changes from lakhs made in the 1700's in
an attempt to make the siddur sound more Biblical. It is done mostly where
there is not a big hefsek. R' Zalman Henne and R' Yitzhak Satanov were
leaders in this field and Heidenheim/Roedelheim and then Avodat Yisrael
accepted most of these "corrections" followed by other Ashkenaz siddurim.
