This covers obtaining the ISO, connecting to Wi-Fi, partitioning, formatting, mounting, installing, setting up encryption and installing GRUB, in one article. Also includes some tips, like quickly mounting from install medium. Maybe this helps someone.
The Bootloader itself cannot be encrypted afaik, but the Kernel and initrd can reside on a LUKS Volume (GRUB_USE_CRYPTODISK).

I don't think that a kernel and initrd necessarily need to be encrypted
