Here are some ideas :

1) you should add a specific character before every lines that start by a number.
this way, you can use this character as a record separator and retrieve questions by there records number (easy using awk)

2) you should store the total number of record/questions into a variable, because you may need it :
- if you are at the last questions and press N "Next" into the menu, you could therefore go to question 1
- if you are in question 1 and press P "Previous" then you could easily go to the last equestions.

3) Since you are going to do repeted task (display question and ask choice) you should consider building that call into a function that would take (for example) the questions number as arguments

dpkg-reconfigure

DPKG-RECONFIGURE(8)						      Debconf						       DPKG-RECONFIGURE(8)

NAME

       dpkg-reconfigure - reconfigure an already installed package

SYNOPSIS

	dpkg-reconfigure [options] packages

DESCRIPTION

       dpkg-reconfigure reconfigures packages after they have already been installed. Pass it the names of a package or packages to reconfigure.
       It will ask configuration questions, much like when the package was first installed.

       If you just want to see the current configuration of a package, see debconf-show(1) instead.

OPTIONS

       -ftype, --frontend=type
	   Select the frontend to use. The default frontend can be permanently changed by:

	    dpkg-reconfigure debconf

	   Note that if you normally have debconf set to use the noninteractive frontend, dpkg-reconfigure will use the dialog frontend instead,
	   so you actually get to reconfigure the package.

       -pvalue, --priority=value
	   Specify the minimum priority of question that will be displayed.  dpkg-reconfigure normally shows low priority questions no matter what
	   your default priority is. See debconf(7) for a list.

       --default-priority
	   Use whatever the default priority of question is, instead of forcing the priority to low.

       -u, --unseen-only
	   By default, all questions are shown, even if they have already been answered. If this parameter is set though, only questions that have
	   not yet been seen will be asked.

       --force
	   Force dpkg-reconfigure to reconfigure a package even if the package is in an inconsistent or broken state. Use with caution.

       --no-reload
	   Prevent dpkg-reconfigure from reloading templates. Use with caution; this will prevent dpkg-reconfigure from repairing broken templates
	   databases.  However, it may be useful in constrained environments where rewriting the templates database is expensive.

       -h, --help
	   Display usage help.
