Little preseed questions

Hello

Please, I need some (little) help in some preseeds. I'm searching for this questions in documentation and I havn't found anything. Would you say if exist some preseed (or preseeds) to get:

    a) Save the installationlog log (/var/log/syslog and partman files) in some location
    b) Change the default grub entry name "Debian GNU/Linux kernel <kernel number>" to a diferent string? (like d-i debian-installer/add-menu-opts string "Newpreseeded Debian")
    c) Enable/Disable show grub menu (the "hiddenmenu" entry), default entry o timeout?
    d) The preseed to add kernel parameters (d-i debian-installer/add-kernel-opts string ) is compatible with lilo?
    e) The name of multipackages selections are?
    - File Server (file-server)
    - Mail Server (mail-server)
    - SQL Server (sql-database)
    - LAMP (lamp)
    - DNS (dns-server)
    - Laptop (laptop)
    - Print-server (print-server)
    - Web-server (web-server)
    f) Don't start X-server (or the login manager gdm/kdm) automatically on boot system? (like "xserver-xorg xserver-xorg/enable-server boolean false")

Sorry for my english. I'm sorry if are a lot of questions but I can't find on other way this answers.

Thanks a lot in advance.
