Installing the packages

[Ricardo Gabriel Herdt]

    Debianers,

   I installed Debian 2.2 base system and when the computer asked me which
packages I want to install I canceled dselect to do it after. Now I want to
install the packages but don't select one by one, select the tasks and
profiles. How can I do this?
   And I want to install the rest of the system after midnight by the Internet.
Is there any way to program the apt to start installing the programs after
midnight? How?      
          Thanks,
    Ricardo Gabriel Herdt
