I presume you mean for external representation purposes, in which case
just use the %d format. Otherwise, reading a hex number converts it
automatically, so you don't need to bother about the internal
representation.

Use the %d format again.

Type "C-h v read-quoted-char-radix RET" etc. and you will be shown the
documentation of the variable.

"M-x set-variable RET read-quoted-char-radix RET <value> RET"

"C-k C-x =".
Sounds like you should read the basic parts of the Emacs manual and
the Elisp manual, before you start coding in Lisp.
