Answer 1

There is a function input(prompt [, text [, completion]]):

The result is a String, which is whatever the user typed on the command-line. The {prompt} argument is either a prompt string, or a blank string (for no prompt). A '\n' can be used in the prompt to start a new line.

(from :help input()).

For things like :grep!, you'll probably have to build the command using a string expression and then :execute it.
