Yes, rust-analyzer can run without it but you need rust-src if you want to
have code completion via LSP for the Rust standard library.
Excerpt from the docs : https://rust-analyzer.github.io/
manual.html#toolchain
"Additionally, rust-analyzer needs the sources of the standard library. If
the source code is not present, rust-analyzer will attempt to install it
automatically."

Yes, rust-analyzer is decoupled from rustc version : the project releases
a new version each week (latest version = 2023-02-27).
